packing a dialog to the correct size [message #631629]

This seems to be a basic question but I couldn't find the right answer on forums.

I am extending TitleAreaDialog and have a Composite as the dialog area which should be packed and the rest of the dialog contents should be packed around it.

I know I can override getInitialSize() and set a fixed size but I fear this size will be incorrect on other platforms than the one I'm using (windows 7).

I already tried adding getShell().setSize(getShell().computeSize(SWT.DEFAULT, SWT.DEFAULT)); to createDialogArea and alternatively overriding getInitialSize to return getShell().computeSize(SWT.DEFAULT, SWT.DEFAULT).

In both cases my dialog gets too large: there is a gray area above the ok button.

why don't you try using grabExcessVerticalSpace and grabExcessHorizontalSpace

You can use the following for your dialog area which you want to be packed:-

GridData data = new GridData();
data.grabExcessVerticalSpace = true;
data.grabExcessHorizontalSpace = true;

For the remaining dialog area

GridData data = new GridData();
data.grabExcessVerticalSpace = false;
data.grabExcessHorizontalSpace = true;
