[ https://issues.jboss.org/browse/JBIDE-25836?page=com.atlassian.jira.plugi... ] Rob Stryker commented on JBIDE-25836: ------------------------------------- So, it's disappearing as proper on linux. We have code to hide it once the new file-chooser is opened: {code} Listener hideUnfocusedPopup = new Listener() { public void handleEvent(final Event event) { Display.getDefault().asyncExec(new Runnable() { public void run() { Widget w = event.widget; Control control = Display.getDefault().getFocusControl(); if (control == null || (control != getTree() && control != popupTable)) { popupShell.setVisible(false); } } }); } }; {code} And this is the stack trace showing the focusOut event is called which then hides the shell: {code} Shell.setVisible(boolean) line: 2359 RuntimeCheckboxTreeViewer$5$1.run() line: 180 RunnableLock.run(Display) line: 37 UISynchronizer(Synchronizer).runAsyncMessages(boolean) line: 182 Display.runAsyncMessages(boolean) line: 4497 Display.idleProc(long) line: 3194 OS._gtk_dialog_run(long) line: not available [native method] OS.gtk_dialog_run(long) line: 6940 FileDialog.openChooserDialog() line: 349 FileDialog.open() line: 300 MissingMinishiftResolutionProvider$MissingMinishiftResolution.getFile(File, Shell) line: 52 {code} If the shell is there, it must somehow not be getting the focusOut event during FileDialog.open(). -- This message was sent by Atlassian JIRA (v7.5.0#75005)
