Is there a way to add an Event.ContextClick to a Gui.Window in a Unity Editor script?
The following is my context menu method that I've tried calling from both OnGUI() and my window's WindowFunction (call sites denoted below as "site: no luck"). I have not been able to get the "Success" message to show up unless I'm right clicking directly in the main editor window. If I right click in any of the Gui.Windows I have created, the ContextClick event doesn't show up.
void OnStateContextMenu(){
Event evt = Event.current;
// Ignore anything but contextclicks
if(evt.type != EventType.ContextClick)return;
Debug.Log("Success");
// Add generic menu at context point
GenericMenu menu = new GenericMenu();
menu.AddItem (new GUIContent ("AddState"),false,AddState,evt.mousePosition);
menu.ShowAsContext ();
evt.Use();
}
And the call site(s):
void doWindow(int id){
// OnStateContextMenu(); //site1: no luck
GUI.DragWindow();
}
void OnGUI(){
OnStateContextMenu(); //site2: no luck here either
BeginWindows();
wndRect = GUI.Window(0,wndRect,doWindow,"StateWnd");
EndWindows();
}
Update
For reference, green area responds to right-click, red area does not. But I want it to. The right-click menu I've created has specific actions I only want visible if the mouse cursor right clicks inside one of my windows, the 'Hello' in the image. Note: Ignore the button, right click doesn't work anywhere inside that window.
This might not directly answer your question but should be able to help
You are trying to achieve a rightclick function inside your red box( as shown in picute )
I had a sort alike question a while back but it was not for a rightclick but for a mouseover
so i figured this might be able to help you
string mouseover; // first of i created a new string
if (GUI.Button (new Rect (100,100,200,200),new GUIContent("Load game", "MouseOverOnButton0") ,menutexture ))
{
//added a mousoveronbutton command to my GUIcontent
executestuff();
}
buttoncheck();
}
void buttoncheck()
{
mouseover = GUI.tooltip;
if(mouseover == "MouseOverOnButton0")
{
GUI.Box(new Rect(380,45,235,25),"Not a implemented function as of yet ");
}
}
this code made a new gui box the moment the mouse hitted the box.
If you created the hello in a seperate box you could use this
if(mouseover == hello)
{
if(rightclick == true)
{
execute the stuff you want
}
}
or something like that. Hope this helps a bit atleast
UPDATE
To obtain the rightclick event you will have to use the
if(Event.current.button == 1 && Event.current.isMouse)
You have to place this in the OnGUI to work properly
this way you first trigger the in box part, then check for a right click and execute the stuff you want.

in Unity 5- I am trying to disable a ui.button- once it is clicked. There is a list of buttons- among which- the clicked one will be disabled. But I am not sure, if it is possible to get the event triggering gameobject.
Unity Editor-
Code:
// called from ui.button clicks
public void callThisMethod(string param) {
// how to get the clicked button gameobject here
}
Just Add another event to return the button
public Button ButtonPressed(Button ThisButton)
{
return ThisButton;
}
You can add something like this to your code:
public Button yourButton;
public void yourButtonClicked(){
yourButton.interactable = false;
}
Assign your button to the Button object in inspector. Then where it says "On Click()" in the image you have above, select the script the above code is added to, and select the "yourButtonClicked()" function. That will disable the button once it is clicked.
To get your clicked button game object, you can use: EventSystem.current.currentSelectedGameObject
Pass the gameObject of the button as a parameter while your are adding event listener to the UI button.
Hope that helps:
GameObject myButtonGameObject = myButton.gameObject;
myButton.onClick.AddListener(() => {LogName(myButtonGameObject); });
public void LogName(GameObject buttonGameObject = null){
Debug.Log(myButtonGameObject);
}
Note: The given approach is useful, when you need to dynamically show the clicked buttons name, but if you know the exact button, you can make a public field for the myButton and get the name without passing any parameters.
I want to give the filter button a right click function that when I right click it, it will clear all the grid criteria.
setFilterOnKeypress(false);
setFilterByCell(true);
setFilterButtonPrompt("Left click to filter, right click to clear all texts.");
Button button = new Button();
button.addClickHandler(new ClickHandler()
{
#Override
public void onClick(ClickEvent event)
{
if (event.isRightButtonDown())
{
SC.warn("right clicked");
clearCriteria();
}
}
});
setFilterButtonProperties(button);
This is not working, any ideas on why it isnt working?
Keep the functionality separate. There is no meaning of mixing two different tasks on the same button. Think from the end user's perspective.
Read more on your another post Pass a handler to filter button property that is some what asked in the same context.
I don't see an event in the Bing map API v7 that will surface a double click event. Is there a way to do this? Assuming there isn't native support that I missed, I think I will have to write my own double click handler with a timer.
I had also a problem with the click-events. In facts, the normal click-event also fires during a double-click event. That is why I had to implement my own double-click handler. My approach can be translated to the rigth click, because I am only using the single-click event, which is also available for the right mouse button.
//Set up my Handler (of course every object can be the target)
Microsoft.Maps.Events.addHandler(map, 'click', Click);
//count variable, that counts the amount of clicks that belong together
myClick=0;
//A click fires this function
function click (e)
{
//If it is the first click of a "series", than start the timeout after which the clicks are handled
if (myClick == 0)
{
//Target have to be buffered
target= e;
//accumulate the clicks for 200ms and react afterwards
setTimeout("reaction(target)", 200);
}
//count the clicks
myClick = myClick+1;
}
//At the end of timeout check how often a click has been performed and react
function reaction(e)
{
if (myClick==1)
{
alert("Single Click!");
}
else (myClick==2)
{
alert("Double click!");
}
else (myClick==3)
{
alert("Tripple click");
}
//reset ClickCount to zero for the next clicks
myClick = 0;
}
Moreover it might be interesting to remove the standart double-click behaviour of Bing-Maps, to zoom in. This can be realized by the following code:
Microsoft.Maps.Events.addHandler(map, 'dblclick', function(e){
e.handled = true;
});
If you only use double click event
Microsoft.Maps.Events.addHandler(this.map, 'dblclick', functionHandler)
should solve the problem
I attached a listener to the Shell on SWT.MouseUp and SWT.MouseDown events, but the handleEvent method never gets fired. I tried clicking at many places on the window, but it doesn't get even to the System.out.println(..) in the code below...
Do you spot any error here?
Thank you!
//c is a Composite.
final Listener l = new Listener(){
public void handleEvent(Event event) {
System.out.println("Got event. "+event);
Rectangle rect = c.getBounds();
if (rect.contains(event.x, event.y)){
if((Boolean)c.getData("selected")){
c.setData("selected", Boolean.FALSE);
}else{
c.setData("selected", Boolean.TRUE);
}
}
}
};
c.getShell().addListener(SWT.MouseUp, l);
c.getShell().addListener(SWT.MouseDown, l);
(This composite is inside an Eclipse editor that uses the Forms Toolkit)
Regards,
-Pradyumna
By writing
c.getShell().addListener(SWT.MouseUp, l);
c.getShell().addListener(SWT.MouseDown, l);
you add the listeners to the shell only! Clicking on a child of the shell does not trigger an event for c.getShell(). Try to click near the border of the window and watch out for your trace message.
If you want to get events for the clicks on c, you have to add listeners to c via c.addListener(.). If you do that, you won't need the condition rect.contains(event.x, event.y) because you know, that the click happened on c.
I am using a TableViewer with a content provider, label provider, a ICellModifier and TextCellEditors for each column.
How can I add arrow key navigation and cell editing when the user selects the cell? I would like this to be as natural a behavior as possible.
After looking at some of the online examples, there seems to be an old way (with a TableCursor) and a new way (TableCursor does not mix with CellEditors??).
Currently, my TableViewer without a cursor will scroll in the first column only. The underlying SWT table is showing cursor as null.
Is there a good example of TableViewer using CellEditors and cell navigation via keyboard?
Thanks!
I don't know if there is a good example. I use a cluster of custom code to get what I would consider to be basic table behaviors for my application working on top of TableViewer. (Note that we are still targetting 3.2.2 at this point, so maybe things have gotten better or have otherwise changed.) Some highlights:
I do setCellEditors() on my TableViewer.
On each CellEditor's control, I establish what I consider to be an appropriate TraverseListener. For example, for text cells:
cellEditor = new TextCellEditor(table, SWT.SINGLE | getAlignment());
cellEditor.getControl().addTraverseListener(new TraverseListener() {
public void keyTraversed(TraverseEvent e) {
switch (e.detail) {
case SWT.TRAVERSE_TAB_NEXT:
// edit next column
e.doit = true;
e.detail = SWT.TRAVERSE_NONE;
break;
case SWT.TRAVERSE_TAB_PREVIOUS:
// edit previous column
e.doit = true;
e.detail = SWT.TRAVERSE_NONE;
break;
case SWT.TRAVERSE_ARROW_NEXT:
// Differentiate arrow right from down (they both produce the same traversal #*$&#%^)
if (e.keyCode == SWT.ARROW_DOWN) {
// edit same column next row
e.doit = true;
e.detail = SWT.TRAVERSE_NONE;
}
break;
case SWT.TRAVERSE_ARROW_PREVIOUS:
// Differentiate arrow left from up (they both produce the same traversal #*$&#%^)
if (e.keyCode == SWT.ARROW_UP) {
// edit same column previous row
e.doit = true;
e.detail = SWT.TRAVERSE_NONE;
}
break;
}
}
});
(For drop-down table cells, I catch left and right arrow instead of up and down.)
I also add a TraverseListener to the TableViewer's control whose job it is to begin cell editing if someone hits "return" while an entire row is selected.
// This really just gets the traverse events for the TABLE itself. If there is an active cell editor, this doesn't see anything.
tableViewer.getControl().addTraverseListener(new TraverseListener() {
public void keyTraversed(TraverseEvent e) {
if (e.detail == SWT.TRAVERSE_RETURN) {
// edit first column of selected row
}
}
});
Now, how exactly I control the editing is another story. In my case, my whole TableViewer (and a representation of each column therein) is loosely wrapped up in a custom object with methods to do what the comments above say. The implementations of those methods ultimately end up calling tableViewer.editElement() and then checking tableViewer.isCellEditorActive() to see if the cell was actually editable (so we can skip to the next editable one if not).
I also found it useful to be able to programmatically "relinquish editing" (e.g. when tabbing out of the last cell in a row). Unfortunately the only way I could come up with to do that is a terrible hack determined to work with my particular version by spelunking through the source for things that would produce the desired "side effects":
private void relinquishEditing() {
// OMG this is the only way I could find to relinquish editing without aborting.
tableViewer.refresh("some element you don't have", false);
}
Sorry I can't give a more complete chunk of code, but really, I'd have to release a whole mini-project of stuff, and I'm not prepared to do that now. Hopefully this is enough of a "jumpstart" to get you going.
Here is what has worked for me:
TableViewerFocusCellManager focusCellManager = new TableViewerFocusCellManager(tableViewer,new FocusCellOwnerDrawHighlighter(tableViewer));
ColumnViewerEditorActivationStrategy actSupport = new ColumnViewerEditorActivationStrategy(tableViewer) {
protected boolean isEditorActivationEvent(ColumnViewerEditorActivationEvent event) {
return event.eventType == ColumnViewerEditorActivationEvent.TRAVERSAL
|| event.eventType == ColumnViewerEditorActivationEvent.MOUSE_DOUBLE_CLICK_SELECTION
|| (event.eventType == ColumnViewerEditorActivationEvent.KEY_PRESSED && event.keyCode == SWT.CR)
|| event.eventType == ColumnViewerEditorActivationEvent.PROGRAMMATIC;
}
};
I can navigate in all directions with tab while editing, and arrow around when not in edit mode.
I got it working based on this JFace Snippet, but I had to copy a couple of related classes also:
org.eclipse.jface.snippets.viewers.TableCursor
org.eclipse.jface.snippets.viewers.CursorCellHighlighter
org.eclipse.jface.snippets.viewers.AbstractCellCursor
and I don't remember exactly where I found them. The is also a org.eclipse.swt.custom.TableCursor, but I couldn't get that to work.
Have a look at
Example of enabling Editor Activation on a Double Click.
The stuff between lines [ 110 - 128 ] add a ColumnViewerEditorActivationStrategy and TableViewerEditor. In my case the I wanted a single click to begin editing so i changed line 115 from:
ColumnViewerEditorActivationEvent.MOUSE_DOUBLE_CLICK_SELECTION
to ColumnViewerEditorActivationEvent.MOUSE_CLICK_SELECTION. After adding this to my TableViewer, the tab key would go from field to field with the editor enabled.
