ToolBar in CoolBar [message #441352]

Hi, All.

I have problems when getting toolbar prefered size. When
I call computeSize(SWT.DEFAULT, SWT.DEFAULT) method it returns
a size of ToolItem not a size of itselt.
So this size goes to CoolItem and if I dinamically add a new ToolBar
in the CoolBar then previous CoolItem changes size so only one ToolItem
is visible.

Have you any suggestions how I can solve this problem?

Thanks for answers.

No one CoolBar shippets work in QNX. I use swt 3.0M6 and also have
tried 3.0 and 3.1M1.

When I call toolbar.pack() or toolbar.computeSize() it returns
incorrect toolbar size. But if I run my program in Linux/Motif it works
fine.

If snippet150 is run using swt3.0M6 then ToolItems are appeared as
points and if snippet150 is run using swt3.0 or higher then only first
ToolItems are visible.

Is it possible to solve this problem?
Does anyone test SWT in QNX before making release?

Please open a bug report in Bugzilla against Platform - SWT.
Please make sure to specify that the problem occurs on QNX (Photon).
Thanks!

More deep look at this problem have shown that problem occurs only if
ToolBar size is calculated before putting it to CoolItem.
So if you change snippet150 method "CoolItem createItem(CoolBar coolBar,
int count)" like this then it works.

static CoolItem createItem(CoolBar coolBar, int count) {
ToolBar toolBar = new ToolBar(coolBar, SWT.FLAT);
for (int i = 0; i < count; i++) {
ToolItem item = new ToolItem(toolBar, SWT.PUSH);
item.setText(itemCount++ +"");
}
CoolItem item = new CoolItem(coolBar, SWT.NONE);
item.setControl(toolBar);
toolBar.pack();
Point size = toolBar.getSize();
Point preferred = item.computeSize(size.x, size.y);
item.setPreferredSize(preferred);
return item;
}

And I am hesitating should I open a new bug?

Interesting.
Yes, I think you should still open the bug report.
Mention that it only happens on QNX, and paste in your workaround.
I think it should be fixed to work no matter when the toolbar size is
calculated.
And while we wait for the fix, your bug report might help someone who may
have the same problem.
Thanks!
