How to control shell size? [message #461437] Thu, 22 September 2005 18:24 Go to next message

Another newbie question, so probably a silly one.

I'm trying to build an SWT app which does its output into a text box. I
don't know how much output there will be in advance, so I'm giving the box
scroll bars. If I don't do anything about the size, it just goes on
expanding downwards with the scroll bars greyed out, and the shell expands
with it until it's taller than the screen, which makes it virtually
impossible to read the text.

If I set the size of the text box each time with code like:

/*
call a subroutine which calls outputText.append several times
*/
textSize=outputText.computeSize(SWT.DEFAULT,SWT.DEFAULT);
textW=Math.min(textSize.x,400);
textH=Math.min(textSize.y,400);
outputText.setSize(textW,textH);
shell.pack(true);
System.out.println("Shell size "+ shell.getSize().y +
", table size " + outputText.getSize().y);

the shell window keeps on expanding each time I call the subroutine until
it's 780 pixels high and the text box 569 pixels. Then the text box goes
down to 400 high and displays a scroll bar but the shell window stays at
780, which is too big for the physical display. Resizing the window does
odd things to the table, which I'm still trying to work out.

Any idea what I'm doing wrong?

Hi Peter,

two possible solutions:
(a) you should have a look into the layout concept of SWT (see articles
in http://www.eclipse.org/articles/). You should use a GidLayout and
give your Text widget a hightHint.

(b) do not use shell.pack but simply shell.setSize(blabla).

Hope that helped,
Friederich
