Hi All,
I am trying to get a JFace dialog to behave correctly but must be doing
something wrong.
In the createDialogArea method below, I try to set the initial size and
location of my dialog.
However this appears to have no effect. Rather, the size seems to be
dependent on the FormData settings that I use when I create the widgets in
the dialog.
Am I doing something wrong or is this functionality just flaky in
JFace/SWT/FormLayout?
Thanks,
Mark
protected Control createDialogArea(Composite parent)
{
FormData formData;
FormData formData2;
Composite area = (Composite) super.createDialogArea(parent);
area.setBounds(100,100,500,500);
FormLayout layout = new FormLayout();
layout.marginHeight = 3;
layout.marginWidth = 3;
area.setLayout(layout);
{
m_text = new Text(area, SWT.BORDER|SWT.MULTI|SWT.WRAP|SWT.V_SCROLL);
formData2 = new FormData();
formData2.top = new FormAttachment(0, 5);
formData2.bottom = new FormAttachment(90, -5);
formData2.left = new FormAttachment(0, 5);
formData2.right = new FormAttachment(100, -5);
m_text.setLayoutData(formData2);
}
{
m_applyButton = new Button(area, SWT.PUSH);
formData = new FormData();
formData.top = new FormAttachment(m_text, 5);
formData.left = new FormAttachment(0, 5);
m_applyButton.setLayoutData(formData);
m_applyButton.setText("Apply Comments");
}
return area;
}

To understand what SWT is doing, create a stand alone SWT example that uses
FormLayout. That will help you determine who is causing the trouble.

It is not clear from your code. Is area a Shell? If not, area is probably
being managed by a layout in parent and setting the bounds will have no
effect because the layout on parent will override your setBounds.
If you are trying to set the position of teh dialog on teh screen, you could
do something like this:
area.getShell().setBounds(100, 100, 500, 500);
Be careful about positioning a dialog. Some people have multiple monitors
and this code may put the dialog in a bizarre location. For more info about
working with multiple monitors, see:
