Re: [platform-swt-dev] SWT JRE 1.5.0 Mac PowerPc

Hi Vinh

Hmm I'm not sure I understand... First question is, why does it works on 
windows and not mac then?

Maybe it is not how I should do (sorry I'm both SWT and java beginner) 
but I create a main form in the class entry point like that:

/public static void main(String[] args) {
       app = new AppMain();
   }
  
public AppMain() {
       mainForm = new MainForm(this);
       mainForm.init();
}/

and then in the MainForm.init(), I do:

/ shell.setLayout(new FillLayout());       
shell.setSize (800, 600);
shell.open();
displayGlobalSettingsForm();
while (!shell.isDisposed()) {
   if (!display.readAndDispatch()) {
       display.sleep();
   }
}
if(appGlobalSettings.isDirty()) {
   appGlobalSettings.save();
}
display.dispose();    /

Is that wrong?

Sorry I dont know what's a UI thread... and I'm not sure what you mean 
by modifying the UI. I see my app and I got my first error when I set a 
path with a browse button, on mac the finder to select the path appears 
and then I see the error in the terminal. While I have none in windows.

What can I do? and do you have some example somewhere of how I should 
properly do things?

Thanks again for your help.
