I've developed an extension some time ago that allows to highlight a section of the scrollbar with the specified color, here is how I do it:
/// <summary>On layout changed analyze the regions and lines and highlight them on the scroll bar if needed.</summary>
private void OnLayoutChanged(object sender, TextViewLayoutChangedEventArgs e)
{
Children.Clear();
int n = AllAdornments.TextAdornment.Regions.Length;
for (int i = 0; i < n; i++)
{
if (AllAdornments.TextAdornment.Regions[i].Adornment != null
&& AllAdornments.TextAdornment.Regions[i].EndLine < e.NewSnapshot.LineCount)
{
var rect = new Rectangle();
var firstLine = e.NewSnapshot.GetLineFromLineNumber(AllAdornments.TextAdornment.Regions[i].StartLine);
var lastLine = e.NewSnapshot.GetLineFromLineNumber(AllAdornments.TextAdornment.Regions[i].EndLine);
double top, bottom;
double firstLineTop;
MapLineToPixels(firstLine, out firstLineTop, out bottom);
SetTop(rect, firstLineTop);
SetLeft(rect, ScrollBarLeftPadding);
MapLineToPixels(lastLine, out top, out bottom);
rect.Height = bottom - firstLineTop;
rect.Width = ScrollBarWidth;
Color color = Communicator.LerpColor(AllAdornments.TextAdornment.UserBackgroundCol,
AllAdornments.TextAdornment.Regions[i].Adornment.Color, ScrollBarIntensity
* AllAdornments.TextAdornment.Regions[i].Adornment.IntensityMult);
color.A = ScrollBarOpacity;
rect.Fill = new SolidColorBrush(color);
Children.Add(rect);
}
}
}
Here is how it looks in Visual Studio:
This worked perfectly for a long time (around 1,5 - 2 years), but when I updated VS four months ago a problem emerged: I can no longer click on the section of the scrollbar margin with the colored Rectangle - the mouse click simply does nothing as long as it is above the colored Rectangle. On the empty section of the scrollbar it works as usual. Before I could not only click on my Rectangle-s, but hold the mouse button down and drag the scrollbar. Is there any way I can bring back this functionality?
Can you try setting rect.IsHitTestVisible = false;

I am using unity 2018.3.7. In my project I have instantiate 25 buttons in the scroll bar..I am scrolling the button. It is working well.
Actually i want freeze the 12 the button.When i scroll the button. The 12 th button should be constantly should be there and other button should scroll go up.
scrolling should be done but the freeze button should be constantly there.
Like Excel. If we freeze the top row. The top row is constantly there and scrolling is happened.
Like that i have to do in unity.
How to Freeze the button in scroll bar.
Edit:
Actually I have uploaded new gif file. In that gif file 2 row is freezed (Row Heading1,Row Heading2, Row Heading3,RowHeading4).
2nd row is constantly there. Rest of the the rows 4 to 100 rows are going up.
Like that i have to do ...
How can i do it..
Though your question still is very broad I guess I got now what you want. This will probably not be exactly the solution you want since your question is quite vague but it should give you a good idea and starting point for implementing it in the way you need it.
I can just assume Unity UI here is the setup I would use. Since it is quite complex I hope this image will help to understand
so what do we have here:
Canvas
has the RowController script attached. Here reference the row prefab and adjust how many rows shall be added
Panel is the only child of Canvas. I just used it as a wrapper for having a custom padding etc - it's optional
FixedRowPanel
Here we will add the fixed rows on runtime
Initially has a height of 0!
Uses anchore pivot Y = 1! This is later important for changing the height on runtime
Uses a Vertical Layout Group for automatically arranging added children
ScrollView - Your scrollview as you had it but
Uses streched layout to fill the entire Panel (except later the reduced space for the fixed rows)
Uses anchor pivot Y = 1! Again important for changing the height and position on runtime later
Viewport afaik it should already use streched anchors by default but not sure so make it
Content
Uses a Vertical Layout Group
Initially has a height of 0 (but I set this in the code anyway) and will grow and shrink accordingly when adding and removing rows
And finally RowPrefab
I didn't add its hierachy in detail but it should be clear. It has a Toggle and a Text as childs ;)
Has the Row script attached we use for storing and getting some infos
Now to the scripts - I tried to comment everything
The Row.cs is quite simple
public class Row : MonoBehaviour
{
// Reference these via the Inspector
public Toggle FixToggle;
public Text FixTogText;
public Text RowText;
public RectTransform RectTransform;
// Will be set by RowController when instantiating
public int RowIndex;
private void Awake()
{
if (!RectTransform) RectTransform = GetComponent<RectTransform>();
if (!FixToggle) FixToggle = GetComponentInChildren<Toggle>(true);
if (!FixTogText) FixTogText = FixToggle.GetComponentInChildren<Text>(true);
}
}
And here is the RowController.cs
public class RowController : MonoBehaviour
{
public Row RowPrefab;
public RectTransform ScrollView;
public RectTransform Content;
public RectTransform FixedRowParent;
public int HowManyRows = 24;
public List<Row> CurrentlyFixedRows = new List<Row>();
public List<Row> CurrentlyScrolledRows = new List<Row>();
// Start is called before the first frame update
private void Start()
{
// initially the content has height 0 since it has no children yet
Content.sizeDelta = new Vector2(Content.sizeDelta.x, 0);
for (var i = 0; i < HowManyRows; i++)
{
// Create new row instances and set their values
var row = Instantiate(RowPrefab, Content);
// store the according row index so we can later sort them on it
row.RowIndex = i;
row.RowText.text = $"Row Number {i + 1}";
// add a callback for the Toggle
row.FixToggle.onValueChanged.AddListener(s => HandleToggleChanged(row, s));
// increase the content's size to fit the children
// if you are using any offset/padding between them
// you will have to add it here as well
Content.sizeDelta += Vector2.up * row.RectTransform.rect.height;
// don't forget to add them to this list so we can easily access them
CurrentlyScrolledRows.Add(row);
}
}
// called every time a row is fixed or unfixed via the Toggle
private void HandleToggleChanged(Row row, bool newState)
{
if (newState)
{
// SET FIXED
// Update the button text
row.FixTogText.text = "Unfix";
// Move this row to the fixedRow panel
row.transform.SetParent(FixedRowParent);
// be default we assume we want the first position
var targetIndex = 0;
// if there are other fixed rows already find the first child of FixedRowParent that has a bigger value
if (CurrentlyFixedRows.Count > 0) targetIndex = CurrentlyFixedRows.FindIndex(r => r.RowIndex > row.RowIndex);
// handle case when no elements are found -> -1
// this means this row is the biggest and should be the last item
if (targetIndex < 0) targetIndex = CurrentlyFixedRows.Count;
// and finally in the hierachy move it to that position
row.transform.SetSiblingIndex(targetIndex);
// insert it to the fixed list and remove it from the scrolled list
CurrentlyFixedRows.Insert(targetIndex, row);
CurrentlyScrolledRows.Remove(row);
// Make the fixed Panel bigger about the height of one row
FixedRowParent.sizeDelta += Vector2.up * row.RectTransform.rect.height;
// Make both the scrollView and Content smaller about one row
Content.sizeDelta -= Vector2.up * row.RectTransform.rect.height;
ScrollView.sizeDelta -= Vector2.up * row.RectTransform.rect.height;
// Move the scrollView down about one row in order to make space for the fixed panel
ScrollView.anchoredPosition -= Vector2.up * row.RectTransform.rect.height;
}
else
{
// SET UNFIXED - Basically the same but the other way round
// Update the button text
row.FixTogText.text = "Set Fixed";
// Move this row back to the scrolled Content
row.transform.SetParent(Content);
// be default we assume we want the first position
var targetIndex = 0;
// if there are other scrolled rows already find the first child of Content that has a bigger value
if (CurrentlyScrolledRows.Count > 0) targetIndex = CurrentlyScrolledRows.FindIndex(r => r.RowIndex > row.RowIndex);
// handle case when no elements are found -> -1
// this means this row is the biggest and should be the last item
if (targetIndex < 0) targetIndex = CurrentlyScrolledRows.Count;
// and finally in the hierachy move it to that position
row.transform.SetSiblingIndex(targetIndex);
// insert it to the scrolled list
CurrentlyScrolledRows.Insert(targetIndex, row);
// and remove it from the fixed List
CurrentlyFixedRows.Remove(row);
// shrink the fixed Panel about ne row height
FixedRowParent.sizeDelta -= Vector2.up * row.RectTransform.rect.height;
// Increase both Content and Scrollview height by one row
Content.sizeDelta += Vector2.up * row.RectTransform.rect.height;
ScrollView.sizeDelta += Vector2.up * row.RectTransform.rect.height;
// Move scrollView up about one row height to fill the empty space
ScrollView.anchoredPosition += Vector2.up * row.RectTransform.rect.height;
}
}
}
Result:
As you can see I can now fix and unfix rows dynamically while keeping their correct order within both according panels.
As you can see in the picture, "Layout0" is selected with dark blue color.
I want to make this box too in my custom editor, but what I actually found is that this is not EditorGUILayout.BeginScrollView and other whatever stuffs.
could someone please tell me the keyword of this selectable box?
I am not entirely sure how the highlighting works but here's how I think it's implemented.
Make a scrollable view using GUILayout.BeginScrollView
Make a vertical view, but with help box style GUILayout.BeginVertical(EditorStyles.helpBox)
For the highlighting, create a blue texture and assign it to a GUIStyle, which you then use for the button. Do this on Awake so you only do this once.
Texture2D texture = new Texture2D(1, 1);
for(int x = 0; x < 1; x++)
{
for(int y = 0; y < 1; y++)
{
texture.SetPixel(x, y, Color.blue);
}
}
texture.Apply();
this.selectedStyle = new GUIStyle();
this.selectedStyle.normal.textColor = Color.white;
this.selectedStyle.normal.background = texture;
Change the buttons to label buttons GUILayout.Button("name", currentSelected ? this.selectedStyle : GUIStyle.label)
I've ran into a small issue developing a picture taker for a VR project. I need to take a screenshot of a specific zone, which is a rectangle with variable width and height. To do that, I have a transform anchored to the top right corner of the bounding box that represents where the picture is going to be taken, and one anchored to the lower right corner.
Here's what it should look like. I've added little red circles to show the transforms's position.
Here's what a screencap using the left eye looks like. It's the same result if I use "both eyes" as a target in the Camera settings.
Here's what a screencap using the right eye looks like. So not only is it too far left or right, it's also a tad too high.
Here's the code that creates the Rect, and here's the code that reads the pixels.
When the Main Camera targets the left eye, there's almost half of the Rect's with as an offset to the left, when it targets the right eye, there's that same offset to the right, when it targets both, there's a softer offset to the left, and all of these have a slight vertical offset upwards.
Any help is appreciated. I'll keep this thread updated if I find anything!
public void SubmitPicture()
{
Vector2 upperLeftPosition = mainCamera.WorldToScreenPoint(upperLeftTransform.position);
Vector2 lowerRightPosition = mainCamera.WorldToScreenPoint(lowerRightTransform.position);
pictureBoxRect.x = upperLeftPosition.x;
pictureBoxRect.y = mainCamera.scaledPixelHeight - upperLeftPosition.y;
pictureBoxRect.width = lowerRightPosition.x - upperLeftPosition.x;
pictureBoxRect.height = lowerRightPosition.y - upperLeftPosition.y;
pictureSnapper.OnInput(AbsoluteRect(pictureBoxRect));
}
public void OnInput(Rect pictureBox)
{
if ((int)pictureBox.width > 0 && (int)pictureBox.height > 0)
{
videoPlayer.Stop();
Texture2D videoTexture = new Texture2D((int)pictureBox.width, (int)pictureBox.height);
videoTexture.ReadPixels(pictureBox, 0, 0);
videoTexture.Apply();
byte[] imageData = videoTexture.GetRawTextureData();
if (debug)
{
byte[] imagePng = videoTexture.EncodeToPNG();
File.WriteAllBytes(Application.dataPath + "/" + savename + ".png", imagePng);
}
}
}
private Rect AbsoluteRect(Rect rect)
{
if (rect.width < 0)
{
rect.x -= rect.width;
rect.width = Mathf.Abs(rect.width);
}
if (rect.height < 0)
{
rect.y += rect.height / 2;
rect.height = Mathf.Abs(rect.height);
}
return rect;
}
Updated to add the picture references.
I have bunifutransition1 that slides my mainpanel from left to right upon clicking showbutton. (It shows the hidden mainpanel.)
What I want is, when I click closebutton, the mainpanel will slide from right to left (to hide the mainpanel again). It seems that bunifuTransition does not have an animation that reverses the animation of VertSlide or HorizSlide.
What should I do to slide my mainpanel from right to left to hide it again on my form?
I was having the exact same issue but upon reading your question the answer finally became prevalent in my mind. The solution here is to stop using BunifuTranisition altogether and go for the good ol' for loops and the other mods, puns intended.
int originalWidth = panel.width;
int menuClicksIndex = 0;
private void beginTransition()
{
if (menuClickIndex % 2 == 0)
{
//This executes on the first click
for(int i = originalWidth-1; i>=0; i--)
{
// Loops from original width to 0
panel.Width = i;
}
}
else
{
for (int i = 0; i <= originalWidth; i++)
{
panel.Width = i;
}
}
menuClickIndex++;
}
This works for me but it glitches on the way back from left to right. So a mixed version with BunifuTransitions for the opener and the for loop for the closer would be the ideal solution here.
UPDATE 1: It seems as if while changing the width of the panel from 0 to say, 350, the content inside the panel doesn't render until the height is set to the max, but while decreasing the height from 350 to 0, the content is already rendered and so it seems smooth to close but cluttery to open, hence probably explaining why BunifuTransition is unable to do that as well.
Solution Here.
Just go bunifu transition properties
Open or dragdown DefaultAnimation. Find this option in menu ("Side Coeff") It Show value of
X and Y {X=1, Y=0} . You just change this value {X=-1, Y=0}.
Then Start your project and check. Your slider sliding left to right. :)
Keep enjoy.

Haris Ali
Use this command: bunifuTransition1.HideSync(guna2Panel1); before any code on event button click!
I would like to display a quadratic GridPane inside a window. The window can have every possible size and normally width and height are not equal. Anyway I would like to display the GridPane as square centered like this:
respectively
Ideally there is a configurable padding around the square. The pictures are taken from a canvas approach, but I want to switch to standard controls. Can anyone give me some hints how to achieve this?
One way to achieve an squared layout for your grid for any resolution of your window is rescaling it to use the maximum size of the window (after some padding), while keeping the squared size.
Instead of a GridPane, a simple Group is more flexible for moving its children, though it requires manual layouting of them.
This simple snippet is based on the JavaFX implementation of the 2048 game you can find here. It uses styleable rectangles to create a grid, and over them the 'tiles' are added. To find out more about styling, layouting or tile movement, go to the refered link.
private static final int NUM_CELLS = 15;
private static final int CELL_SIZE = 50;
private static final int TILE_SIZE = CELL_SIZE-15;
private final static int MARGIN = 20;
#Override
public void start(Stage primaryStage) {
// create background square grid
Group gridGroup = new Group();
IntStream.range(0,NUM_CELLS).boxed().forEach(i->
IntStream.range(0,NUM_CELLS).boxed().forEach(j->{
Rectangle cell = new Rectangle(i * CELL_SIZE, j * CELL_SIZE, CELL_SIZE, CELL_SIZE);
cell.setFill(Color.WHEAT);
cell.setStroke(Color.GREY);
gridGroup.getChildren().add(cell);
})
);
// Add grid to board
Group board = new Group(gridGroup);
// add random tiles to board
IntStream.range(0,NUM_CELLS).boxed().forEach(i->
IntStream.range(0,NUM_CELLS).boxed().forEach(j->{
if(i==j || NUM_CELLS-i-1==j){
Label label = new Label();
label.setMinSize(TILE_SIZE, TILE_SIZE);
label.setPrefSize(TILE_SIZE, TILE_SIZE);
label.setMaxSize(TILE_SIZE, TILE_SIZE);
label.setStyle("-fx-background-color: red; -fx-background-radius: 50");
label.setLayoutX((i+0.5)*CELL_SIZE-TILE_SIZE/2);
label.setLayoutY((j+0.5)*CELL_SIZE-TILE_SIZE/2);
board.getChildren().add(label);
}
})
);
Bounds gameBounds = board.getLayoutBounds();
StackPane root = new StackPane(board);
// Listener to rescale and center the board
ChangeListener<Number> resize = (ov, v, v1) -> {
double scale = Math.min((root.getWidth() - MARGIN) / gameBounds.getWidth(),
(root.getHeight() - MARGIN) / gameBounds.getHeight());
board.setScaleX(scale);
board.setScaleY(scale);
board.setLayoutX((root.getWidth() - gameBounds.getWidth()) / 2d);
board.setLayoutY((root.getHeight() - gameBounds.getHeight()) / 2d);
};
root.widthProperty().addListener(resize);
root.heightProperty().addListener(resize);
Scene scene = new Scene(root);
// Maximum size of window
Rectangle2D visualBounds = Screen.getPrimary().getVisualBounds();
double factor = Math.min(visualBounds.getWidth() / (gameBounds.getWidth() + MARGIN),
visualBounds.getHeight() / (gameBounds.getHeight() + MARGIN));
primaryStage.setScene(scene);
primaryStage.setWidth((gameBounds.getWidth() + MARGIN) * factor);
primaryStage.setHeight((gameBounds.getHeight() + MARGIN) * factor);
primaryStage.show();
}
And this is how it will look like after some window resizing:
