I am just learning scalaFX/javaFX after years with swing and months with scalaSwing. ScalaSwing had a few little issues that I felt weren't worth dealing with given the opportunity to update to something current. It Doesn't surprise me that I am having issues, but I am concerned.
Is this a problem with something I'm doing? I need black backgrounds and this seems to be failing and not telling me why.
I can sort of get this to work if I add the button first then a rectangle. I have tried wrapping the rectangle, but that is not the solution.
Thanks!
object Broken extends JFXApp {
stage = new PrimaryStage {
x = 0
y = 0
scene = new Scene {
stylesheets add getClass.getResource("Dark.css").toExternalForm
root = new FlowPane {
padding = Insets(10)
children = List(new Rectangle() {
x = 0
y = 0
width = 100
height = 150
arcHeight = 20
arcWidth = 20
fill = Color.Red
})
}
}
}
}
object Works extends JFXApp {
stage = new PrimaryStage {
x = 0
y = 0
scene = new Scene {
stylesheets add getClass.getResource("Dark.css").toExternalForm
root = new FlowPane {
padding = Insets(10)
children = List(new Button("Works"))
}
}
}
}
With this as Dark.css (file) in the same package
//Dark.css
.root{
-fx-font-size: 14pt;
-fx-font-family: "Courier New";
-fx-base: rgb(25,25,65);
-fx-background: rgb(0, 0, 0);

I have the following graph with 3 datasets. Everything works fine except for one small bug. I want to tooltip to be placed only on the first dataset, as it currently is placed on the average position of all datasets.
Here is a screenshot:
I know that ChartJS has the positioners function (the one below), but I can't figure out how to ignore the other 2 datasets so the tooltip is sticked only to the first line graph
Chart.Tooltip.positioners.top = function (elements, eventPosition) {
const tooltip = this;
return ;
};
You can also define a custom position function for tooltips. like this,
Chart.Tooltip.positioners.custom = function(elements, eventPosition) {
var x = eventPosition.x;
var y = eventPosition.y;
var minDistance = Number.POSITIVE_INFINITY;
var i, len, nearestElement;
var top_element = elements[0];
for (i = 0, len = elements.length; i < len; ++i) {
console.log(elements[i].tooltipPosition().y);
if (elements[i].tooltipPosition().y < top_element.tooltipPosition().y) {
top_element = elements[i];
}
}
var tp = top_element.tooltipPosition();
x = tp.x;
y = tp.y;
return {
x: x,
y: y
};
};
Once done, you can specify it in tooltips.options.

Hope it helps!
I use function
NSViewController.PresentViewControllerAsSheet(NSViewController)
and everything works great, but I would like to have a chance change the position of this sheet (for ex. in the center of parent).
How to do that ?
Ok, I have found solution:
C# code, Xamarin.Mac
controller.PresentViewControllerAsModalWindow(_settingsController);
if (_settingsController.View.Window != null)
{
var x = (_window.Frame.Left) + (_window.Frame.Width / 2) - 400;
var y = (_window.Frame.Top) + (_window.Frame.Height / 2) - 300;
_settingsController.View.Window.SetFrame(new CoreGraphics.CGRect(x, y, 800, 600), true);
_settingsController.View.Window.TitleVisibility = NSWindowTitleVisibility.Hidden;
_settingsController.View.Window.TitlebarAppearsTransparent = true;
_settingsController.View.Window.StyleMask = NSWindowStyle.FullSizeContentView | NSWindowStyle.Borderless;
_settingsController.View.Window.IsMovable = false;
}
is there a way to modify this code for animate cc to make object in the stage and interact with it ?
it is a bit of pain to make drag and drop in createjs for animate cc
there is nothing in the web that describe how to do it for animate cc or flash cc even the documentation has nothing to tell about drag and drop in the canvas
//Stage
var stage = new createjs.Stage("demoCanvas");
//VARIABLES
//Drag Object Size
dragRadius = 40;
//Destination Size
destHeight = 100;
destWidth = 100;
//Circle Creation
var label = new createjs.Text("DRAG ME", "14px Lato", "#fff");
label.textAlign="center";
label.y -= 7;
var circle = new createjs.Shape();
circle.graphics.setStrokeStyle(2).beginStroke("black")
.beginFill("red").drawCircle(0,0, dragRadius);
//Drag Object Creation
//Placed inside a container to hold both label and shape
var dragger = new createjs.Container();
dragger.x = dragger.y = 100;
dragger.addChild(circle, label);
dragger.setBounds(100, 100, dragRadius*2, dragRadius*2);
//DragRadius * 2 because 2*r = width of the bounding box
var label2 = new createjs.Text("HERE", "bold 14px Lato", "#000");
label2.textAlign = "center";
label2.x += 50;
label2.y += 40;
var box = new createjs.Shape();
box.graphics.setStrokeStyle(2).beginStroke("black").rect(0, 0, destHeight, destWidth);
var destination = new createjs.Container();
destination.x = 350;
destination.y = 50;
destination.setBounds(350, 50, destHeight, destWidth);
destination.addChild(label2, box);
//DRAG FUNCTIONALITY =====================
dragger.on("pressmove", function(evt){
evt.currentTarget.x = evt.stageX;
evt.currentTarget.y = evt.stageY;
stage.update(); //much smoother because it refreshes the screen every pixel movement instead of the FPS set on the Ticker
if(intersect(evt.currentTarget, destination)){
evt.currentTarget.alpha=0.2;
box.graphics.clear();
box.graphics.setStrokeStyle(3)
.beginStroke("#0066A4")
.rect(0, 0, destHeight, destWidth);
}else{
evt.currentTarget.alpha=1;
box.graphics.clear(); box.graphics.setStrokeStyle(2).beginStroke("black").rect(0, 0, destHeight, destWidth);
}
});
//Mouse UP and SNAP====================
dragger.on("pressup", function(evt) {
if(intersect(evt.currentTarget, destination)){
dragger.x = destination.x + destWidth/2;
dragger.y = destination.y + destHeight/2;
dragger.alpha = 1;
box.graphics.clear();
box.graphics.setStrokeStyle(2).beginStroke("black").rect(0, 0, destHeight, destWidth);
stage.update(evt);
}
});
//Tests if two objects are intersecting
//Sees if obj1 passes through the first and last line of its
//bounding box in the x and y sectors
//Utilizes globalToLocal to get the x and y of obj1 in relation
//to obj2
//PRE: Must have bounds set for each object
//Post: Returns true or false
function intersect(obj1, obj2){
var objBounds1 = obj1.getBounds().clone();
var objBounds2 = obj2.getBounds().clone();
var pt = obj1.globalToLocal(objBounds2.x, objBounds2.y);
var h1 = -(objBounds1.height / 2 + objBounds2.height);
var h2 = objBounds2.width / 2;
var w1 = -(objBounds1.width / 2 + objBounds2.width);
var w2 = objBounds2.width / 2;
if(pt.x > w2 || pt.x < w1) return false;
if(pt.y > h2 || pt.y < h1) return false;
return true;
}
//Adds the object into stage
stage.addChild(destination, dragger);
stage.mouseMoveOutside = true;
stage.update();
thanks
I am not exactly sure what you are asking. The demo you showed works fine (looks like it came from this codepen), and it is not clear what you are trying to add. This demo was made directly in code, not with Animate CC - which is really good for building assets, animations, and display list structure, but you should write application code around what gets exported.
There are plenty of documentation and examples online for Drag and Drop, in the EaselJS GitHub, and EaselJS docs:
DragAndDrop demo in GitHub
Live demo on EaselJS demos page
Documentation on pressMove
Tutorial on Mouse Events which includes Drag and Drop
I recommend narrowing down what you are trying to do, show what code or approaches you have tried so far, and posting specific questions here.
Lastly, here is the first part of an ongoing series for working with Animate CC: http://blog.gskinner.com/archives/2015/04/introduction-to-the-flash-cc-html5-canvas-document.html
Cheers.
The main layout of my ScalaFX 8 application consists of a BorderPane. The top attribute contains a menu whereas bottom contains something similar to a status bar. My goal is to display a component for viewing 3D objects in the center of the BorderPane (acting as a SubScene).
stage = new PrimaryStage {
scene = new Scene(900, 900, true, SceneAntialiasing.Balanced) {
root = new BorderPane {
top = createMenu // creates a menu inside of a VBox
center = createViewer // should create a subscene inside of whatever is needed
bottom = createStatusBar // creates a status bar inside of a VBox
}
}
}
I'm trying to create a minimal working example with a SubScene that only consists of black background and a simple sphere, no more, no less. The SubScene should use the whole space that is available in the center of BorderPane and resize accordingly. Unfortunately, I can't make it work.
Since the size of a SubScene is fixed, I assume it is necessary to embed the SubScene in another container (which is able to resize automatically) and bind the dimensions of the SubScene to the dimensions of the container around it.
def createViewer = {
val bp = new BorderPane
val subScene: SubScene = new SubScene(bp, 200, 200, true, SceneAntialiasing.Balanced) {
fill = Color.Black
width <== bp.width
height <== bp.height
content = new Sphere(3) { material = new PhongMaterial(Color.Red) }
camera = new PerspectiveCamera(true) { ... }
}
bp.center = subScene
subScene
}
The result looks like this:
Two obvious problems:
The SubScene keeps the fixed size from its constructor. In neither "maximizes" in the center of the outer BorderPane, nor does it do anything when the window gets resized
There is the red dot, but the bottom right corner of the SubScene is not black (?)
My assumption is that I have some problems understanding what the root element of the SubScene really is and what it does. I found another thread for JavaFX with a similar problem, this solution distinguishes between the root element of the SubScene (I'm not sure where that element comes from) and the Pane but I couldn't apply it to my case. Any help is appreciated. Thanks.
the idea here is to get the read only properties for the top level scene there is probably a more elegant way to do this, but this works
scene = new Scene(900, 900, true, SceneAntialiasing.Balanced) {
// these are read only properties for the scene
var tmpw = this. width
var tmph = this. height
root = new BorderPane {
top = new HBox {
content = new Label {
text = "menu"
}
}
center = createView(tmpw, tmph)
}
}
width onChange show
height onChange show
}
the idea here is to bind the read only properties to the properties of the subscene, then
the subscene will re-size there is probably a way to avoid the 'this' key-word.
I have tested this and the subscene re-sizes with the parent scene. I have omitted the PerspectiveCamera code block as you did not include what you were using
def createView(boundWidth : ReadOnlyDoubleProperty, boundHeight : ReadOnlyDoubleProperty): BorderPane = {
new BorderPane {
center = new SubScene(boundWidth.get(), boundHeight.get(), true, SceneAntialiasing.Balanced) {
fill = Color.BLACK
content = new Sphere(3) { material = new PhongMaterial(Color.RED) }
camera = new PerspectiveCamera(true)
// bind the subscene properties to the parents
this.width.bind(boundWidth.add(-200))
this.height.bind(boundHeight.add(-200))
}
}
}
I'm working on a browser that's running on Geckofx, and well I can't find a way to change the color of the TabControl
I don't want to change the tab page, I want to change the container.
Here's what I mean:
This is what i'm trying to do:
And this is where i'm at:
I'm already using this for the tabs
private void tabControl_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)
{
{
TabPage CurrentTab = tabControl.TabPages[e.Index];
Rectangle ItemRect = tabControl.GetTabRect(e.Index);
SolidBrush FillBrush = new SolidBrush(Color.Red);
SolidBrush FBG = new SolidBrush(Color.Black);
SolidBrush TextBrush = new SolidBrush(Color.Green);
StringFormat sf = new StringFormat();
sf.Alignment = StringAlignment.Center;
sf.LineAlignment = StringAlignment.Center;
if (System.Convert.ToBoolean(e.State & DrawItemState.Selected))
{
FillBrush.Color = Color.Black;
TextBrush.Color = Color.Green;
ItemRect.Inflate(0, 0);
}
if (tabControl.Alignment == TabAlignment.Left || tabControl.Alignment == TabAlignment.Right)
{
float RotateAngle = 90;
if (tabControl.Alignment == TabAlignment.Left)
RotateAngle = 270;
PointF cp = new PointF(ItemRect.Left + (ItemRect.Width / 3), ItemRect.Top + (ItemRect.Height / 5));
e.Graphics.TranslateTransform(cp.X, cp.Y);
e.Graphics.RotateTransform(RotateAngle);
ItemRect = new Rectangle(-(ItemRect.Height / 3), -(ItemRect.Width / 3), ItemRect.Height, ItemRect.Width);
}
e.Graphics.FillRectangle(FillBrush, ItemRect);
e.Graphics.DrawString(CurrentTab.Text, e.Font, TextBrush, (RectangleF)ItemRect, sf);
e.Graphics.ResetTransform();
FillBrush.Dispose();
TextBrush.Dispose();
}
}
I just have no idea how to change the color of the TabControl
I've looked over online everywhere and the examples either made 0 sense whatsoever or did not work.
I know it's possible from the example i've seen
Can anyone help?
TabControl have the propertie BackColor, from Control. Maybe if nothing work, try to set the DefaultBackColor to the color you need for your TabControl?
Look at this : http://msdn.microsoft.com/en-us/library/system.windows.forms.control.defaultbackcolor.aspx
