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.

In swt, there's only one UI thread. Meaning all things modify the UI
in some form must go through that one thread. That thread is usually
where you created your display object. You're getting invalid thread
access, it means that you are trying to modify the UI in a non-UI
thread. In order to modify the UI thread, you need to do something like
Display.getDefault().asyncExec(new Runnable(){
public void run(){
//modify ui Code
}
};
I hope that helps. good luck

Hi everyone,
First post :)
I hope I can find a bit of help. I'm a flash developer (sorry
about that), and I'm building an application with SWT.
So, I'm fairly new to java but the job is almost done. I've
exported an executable jar and when I tried it on Mac (10.4.1) it
didn't work.
I realized I couldn't install the last JRE on a Mac PowerPC... so
back to my windows PC, I installed a JRE 1.5.0, created a new
workspace in eclipse with JRE 1.5.0, set a new project again with
JRE 1.5.0 and export again my executable jar.
When I tried it on the mac, it is getting better as I can see my
app! But I've got bugs with it and it is not working at all. I've
pasted an example error I got below. As I'm fairly new to java, I
dont know what I can do. I believe the SWT jar I use is too
advanced for the JRE? Should I find other SWT for mac? and where?
Or do I have something wrong in my code?
Well any advice or hunt would be really great...
Thanks a lot.
Romu
