| Re: [platform-ui-dev] Non-modal dialogs, API to determine if dialog is already open |
Unfortunately this isn't an API promise (I don't think). If we're going to start relying on it, maybe we should make it one.
Thanks everyone for the fruitful discussion and especially to Brian
for pointing out the solution.
Checking for an open dialog is very easy with Brians tip:
Shell[] shells = Display.getCurrent().getShells();
for (Shell shell : shells) {
if (shell.getData() instanceof YourWizardClass) {
// as an example give focus to it
shell.forceActive();
// do more stuff
}
Best regards, Lars
