Found in the build: I20131209-2000 The workaround for the issue is restarting the Eclipse after modifying the 3.x theme with the 'Window->Preferences->Colors and Fonts' preference page and before switching to other CSS stylesheet with the 'Window->Preferences->Appearance' one. Probably the issue here is caused by the out-of-synchronization stylesheets and partial applying the new CSS stylesheet (after switching the CSS theme the user has to restart the Eclipse to get full effect) so maybe synchronizing it would be another workaround for it. I haven't checked it Daniel Gerrit review link: https://git.eclipse.org/r/#/c/19633/ Daniel This IAE renders the workbench unusable PW I've released the fix as http://git.eclipse.org/c/platform/eclipse.platform.ui.git/commit/?id=05044a55787792abee37f4adaef63c63198bbae5 Now the user will get the popup "must restart eclipse" and the CTabFolders won't be hosed. We need to overhaul the CSS engine approach to resource management in bug 423813 PW Verified in the build: I20131211-2000 Daniel |
Created attachment 238234 [details] The CSS stylesheet that enables the CSS bridge Steps to reproduce the issue: 1) Enable the CSS bridge functionality by using the CSS stylesheet attached to the bug 2) Start the Eclipse, open the ColorAndFontPreferencePage dialog (Window->Preferences->Colors and Fonts) and do some changes in the 3.x theme. Close dialog 3) Open the ViewsPreferencePage dialog (Window->Preferences->Appearance) and start to switch between CSS stylesheets. Switch between those that use the Font/Color definitions and others that don't use it 4) After applying the new change and closing the 'Restart is required for the theme change to take full effect' message box you will get the IllegalArgumentException (Argument not valid -> SWT.ERROR_GRAPHIC_DISPOSED): java.lang.IllegalArgumentException: Argument not valid at org.eclipse.swt.SWT.error(SWT.java:4400) at org.eclipse.swt.SWT.error(SWT.java:4334) at org.eclipse.swt.SWT.error(SWT.java:4305) at org.eclipse.swt.graphics.GC.setFont(GC.java:4403) at org.eclipse.swt.custom.CTabFolder.onPaint(CTabFolder.java:1981) at org.eclipse.swt.custom.CTabFolder$1.handleEvent(CTabFolder.java:289) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4351) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1061) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1085) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1070) at org.eclipse.swt.widgets.Composite.WM_PAINT(Composite.java:1491) at org.eclipse.swt.widgets.Control.windowProc(Control.java:4667) at org.eclipse.swt.widgets.Display.windowProc(Display.java:5014) at org.eclipse.swt.internal.win32.OS.RedrawWindow(Native Method) at org.eclipse.swt.widgets.Control.update(Control.java:4436) at org.eclipse.swt.widgets.Display.update(Display.java:4875) at org.eclipse.jface.window.Window.runEventLoop(Window.java:834)
