I am trying to show a custom context menu when I right click on a row in a TreeView.
treeView.button_press_event.connect ((event) => {
if (event.type == EventType.BUTTON_PRESS && event.button == 3) {
Gtk.Menu menu = new Gtk.Menu ();
Gtk.MenuItem menu_item = new Gtk.MenuItem.with_label ("Add file");
menu.add (menu_item);
menu.show ();
}
});
It doesn't show anything. If I debug a message there I can see the block is being executed when right clicking on a row in the TreeView. I tried show_all () with no success either. popup_at_pointer () is available only on Gtk+ 3.22 and later versions. I am using Gtk+ 3.18.
Is there any way to show a custom menu when right clicking a row on a Gtk.TreeView?
Found out one has to attach the Gtk.Menu to a widget using attach_to_widget () and then use show_all () before calling the only method to show the menu available in Gtk+ 3.18 which is popup (...). popup (...) is deprecated since Gtk+ 3.22, but it is the only method available in Gtk+ 3.18.
Here is the code
treeView.button_press_event.connect ((event) => {
if (event.type == EventType.BUTTON_PRESS && event.button == 3) {
Gtk.Menu menu = new Gtk.Menu ();
Gtk.MenuItem menu_item = new Gtk.MenuItem.with_label ("Add file");
menu.attach_to_widget (treeView, null);
menu.add (menu_item);
menu.show_all ();
menu.popup (null, null, null, event.button, event.time);
}
});

I think you need the older style gtk_menu_popup.

Is there a way to detect a CTRL-click on a ToolItem? I want to distinguish between CTRL+Click and normal mouse click.
ToolBar toolbar= new ToolBar(parent, SWT.NONE);
ToolItem saveToolItem = new ToolItem(toolbar, SWT.PUSH);
...
saveToolItem.addSelectionListener(SelectionListener.widgetSelectedAdapter(e -> {
// if CTRL+Click {
// specialSave();
// } else
normalSave();
}));
The SelectionEvent passed to the event (in e in your code) has a stateMask field including the modifier keys being pressed. The SWT.CTRL constant for Ctrl.
So:
if ((e.stateMask & SWT.CTRL) == SWT.CTRL)
Tests for the Ctrl key being pressed
I am using the ckEditor along with GWT and SmartGWT. I have a problem that whenever the ckEditor displays a dialog (e.g. link button, table button), although the items in the dialog gain focus (input texts work fine, I can write inside them), the dropdowns (select elements) when clicking on them, do not expand to show their option items (they expand only when they have focus and user hits "spacebar"). This happens only in firefox and chrome (latest versions) while on IE11 it works as expected.
Note that I am already aware of the "focus" problem existing if a ckEditor instance exists in a GWT/jquery modal and I have already included a fix:
$wnd.CKEDITOR.on('dialogDefinition', function (evt) {
var dialog = evt.data.definition.dialog;
dialog.on('show', function () {
var element = this.getElement();
var labelledby = element.getAttribute('aria-labelledby');
var nativeElement = $wnd.document.querySelector("[aria-labelledby='" + labelledby + "']");
nativeElement.onclick = function (evt) {
if ((evt.target.tagName == "INPUT" || evt.target.tagName == "SELECT" || evt.target.tagName == "TEXTAREA") &&
-1 != evt.target.className.indexOf("cke_dialog_ui_input")) {
evt.target.focus();
};
}
});
});
Any hint how I can make the dropdowns to behave correctly? To me it looks like the dropdown element does not receive the click event (although on click it gets focus) or somehow the event's propagation stops unexpectedly.
EDIT
Forgot to mention that the problem appears if the ckEditor instance is inside a modal SmartGWT window. More specifically if I set
Window win = new Window(); //com.smartgwt.client.widgets.Window
win.setIsModal(false);
and then add the DynamicForm form which contains the ckEditor item on that window then the dialog dropdowns work fine, however if I set
win.setIsModal(true);
I get the faulty behavior described above
In case anyone else has the same problem with me, the solution is to call win.hideClickMask() upon show event of the dialog. This can be achieved in many ways depending on how ckEditor is integrated with SmartGWT. In my implementation this is achieved by overriding onDialogShow() as below:
final CKEditor ckEditor = new CKEditor(conf) {
#Override
public void onDialogShow() {
// to overcome the problem that smartgwt modality obstruct the dropdowns of a ckeditor dialog to be pressed
final NodeList<Element> allWindowsWithModalMask = findAllWindowsWithModalMask();
if(allWindowsWithModalMask != null ) {
for(int i =0; i<allWindowsWithModalMask.getLength(); i++) {
Element el = allWindowsWithModalMask.getItem(i);
String id = el.getAttribute("eventproxy");
if(Canvas.getById(id) != null) {
hideClickMask(Canvas.getById(id).getOrCreateJsObj());
}
}
}
}
};
and
protected native NodeList<Element> findAllWindowsWithModalMask() /*-{
return $wnd.document.querySelectorAll("[class='windowBackground']");
}-*/;
protected native void hideClickMask(JavaScriptObject windowCanvas) /*-{
windowCanvas.hideClickMask();
}-*/;
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.
I want to remove the File, edit, Source, Refactor, etc. menus from my RCP application
Can I use hideActionSet() ? or what should I do ?
That's right; in your ApplicationWorkbenchWindowAdvisor, override postWindowOpen().
The tricky bit is usually figuring out the names of the actionsets that you want to remove, but you can use the old standby ALT-SHIFT-F2 (the default keybinding for 'Plugin-in Menu Spy') and click on one of the menu items that you want to remove.
Note that if the menu item is disabled, the spy won't give you any info on it.
public void postWindowOpen() {
runApplicationWorkbenchDelegate();
// remove unwanted UI contributions that eclipse makes by default
IWorkbenchWindow[] windows = PlatformUI.getWorkbench().getWorkbenchWindows();
for (int i = 0; i < windows.length; ++i) {
IWorkbenchPage page = windows[i].getActivePage();
if (page != null) {
// hide generic 'File' commands
page.hideActionSet("org.eclipse.ui.actionSet.openFiles");
// hide 'Convert Line Delimiters To...'
page.hideActionSet("org.eclipse.ui.edit.text.actionSet.convertLineDelimitersTo");
// hide 'Search' commands
page.hideActionSet("org.eclipse.search.searchActionSet");
// hide 'Annotation' commands
page.hideActionSet("org.eclipse.ui.edit.text.actionSet.annotationNavigation");
// hide 'Forward/Back' type navigation commands
page.hideActionSet("org.eclipse.ui.edit.text.actionSet.navigation");
}
}
}
Although the question is old:
Lars Vogel's tutorial about Eclipse Activities shows how to hide entire menus in an RCP application rather than removing single menu-entries.
EDIT:
Alternatively you can use the MenuManager attached to the workbench window to show or hide Menus/Contributions.
Try the following code to hide all menus:
WorkbenchWindow workbenchWin = (WorkbenchWindow)PlatformUI.getWorkbench().getActiveWorkbenchWindow();
MenuManager menuManager = workbenchWin.getMenuManager();
IContributionItem[] items = menuManager.getItems();
for(IContributionItem item : items) {
item.setVisible(false);
}

I have a UI in which when I select an item (in a tree) and then press a button "add", I get a new editor. With each item I can get an editor. (but all have the same ID)
My purpose is to close only the editor of item1, for example, when I press "save". I'm able to close all the editors with: getSite().getWorkbenchWindow().getActivePage().closeAllEditors(true);
But not only the one that I need to close. The following solution helped me:
// Creating and opening
MyObject item1 = ... //create item1
// open editor
myInput = new MyEditorInput(item1)
IDE.openEditor(workbenchPage, myInput, MY_EDITOR_ID);
// Closing
tmpInput = new MyEditorInput(item1)
IEditorReference[] editorReferences = PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getActivePage()
.getEditorReferences();
List<IEditorReference> relevantEditors = new ArrayList<IEditorReference>();
for (IEditorReference iEditorReference : editorReferences) {
if (iEditorReference.getEditorInput().equals(tmpInput)) {
relevantEditors.add(iEditorReference);
}
}
PlatformUI
.getWorkbench()
.getActiveWorkbenchWindow()
.getActivePage()
.closeEditors(
(IEditorReference[]) relevantEditors.toArray(new IEditorReference[relevantEditors
.size()]), true);
….but I still have some problems... As I can open many editors in the same time, and all of them have the same button "save", it happens that I press "save" in editor1 but close editor3... Actually, I save the last editor to be open (thanks to its "item")... this is the problem.. So I'm wondering if there is a way to identify the editor in which the button exists, so that I close it..
Thanks a lot I appreciate any help or hint (Sorry if my questions look easy and not worth being asked, but I'm still a beginner...)
if the Button is rendered in your IEditorPart implementation, you can close the editor directly in your EditorPart.
button.addListener(SWT.Selection, new Listener() {
#Override
public void handleEvent(Event event) {
PlatformUI.getWorkbench().getActiveWorkbenchWindow()
.getActivePage().closeEditor(this, true);
}
});
Selected editor open or another editor can be close using RCP eclipse.
Multiple Editor open at time selected editor can be open or close using RCP eclipse.
IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindow(event);
IWorkbenchPage page = window.getActivePage();
EmployeeEditorInput input = new EmployeeEditorInput();
//List out all the editors open
IEditorReference[] editors = page.getEditorReferences();
for (int i=0; i<editors.length; i++) {
//class : EmployeeEditor
//public static final String Id="rcp_demo.Editor.emp";
if (editors[i].getId().equals(EmployeeEditor.Id)) {
page.activate(editors[i].getEditor(true));
//or
//page.closeEditor(page.getActiveEditor(),true);
System.out.println("Employee Editor Exist");
return null;
}
else
{
page.closeEditor(page.getActiveEditor(), true);
System.out.println("Close other Editor");
}
}
