How to change cursor state based on it location in JAVA?
Hi,
I am working on a GUI in Java SWT. This gui has a dialog box where it does some processing in the worker thread. During this time, I show a busy cursor (spinner). The cursor is in spinning state while the process is going on.
If I move the cursor, to the top of the dialog box where we have the blue narrow area (on Windows it's blue by default) the cursor turns out to be a normal cursor.
So, I would like to have the same behavior when I hover over an icon on the dialog box because the cursor is actionable but the spinner makes it look like it cannot do anything.
How can I change the cursor state based on its location?
Please see my code below: (Line 385)

I tried but it didn't work.

ok. Instead of this, can you please tell me how I can place checkbox button next to the combo in this dialog box (shell)?
Then, I will not need to play with these cursors. I will limit the search by selecting or unselecting this checkbox.
@mccarl: this is the same code you sent me where you used rowlayout to position the combo, table and the two other buttons.
Thanks,

Actually, I put the checkbox and the label using the following code but I cannot change the spacing between the combo and the new label:
I put these lines after line 112:
Can you please tell me how I can put a horizontal spacing?
Thanks,
I put these lines after line 112:
Label label_includeSubmitted = new Label(workspaceComp, SWT.NONE);
label_includeSubmitted.setText("Include submitted changelists: ");
Button selection = new Button(workspaceComp, SWT.CHECK);Can you please tell me how I can put a horizontal spacing?
Thanks,

ok, I did it. Now the problem is how to detect if the checkbox is selected.
for the check box I have this code:
Then this is how I detect the checkbox state: (This code is right after LINE 168)
And this is the line I changed: (LINE 202)
Now the problem is, LINE 202 (in the initial post) says "change modifier to final". Also LINE 5 in this post says the same thing.
If I do that then the code that listens the checkbox above cannot change the "includeSubmittedSelected"
How can I solve this problem?
