Hi,
I'm making a subclass of the JFace dialog. The dialog requires that I use
GridLayout to set up the dialog area. For some reason though, I am unable
to set the size of my widgets. It's extremely frustrating. I'm used to
designing with FormLayout, and have never run into this problem.
I'm likely overlooking something small (or perhaps it's just inexperience
with GridLayout). But I'd like to know how I can set the size of each of
my widgets.
The code sample below illustrates what I'm doing:
protected Control createDialogArea(Composite parent){
Composite comp = new Composite(parent, SWT.NONE);
// Create a new layout using GridLayout
GridLayout layout = new GridLayout();
layout.numColumns = 4;
layout.marginHeight = 3;
layout.marginWidth = 3;
layout.verticalSpacing = 5;
comp.setLayout(layout);
Label lAmount = new Label(comp, SWT.WRAP);
lAmount.setText("Amount:");
GridData data = new GridData();
data.horizontalSpan = 2;
data.horizontalIndent = 10;
lAmount.setLayoutData(data);
Label lDescription = new Label(comp, SWT.WRAP);
lDescription.setText("Description:");
data = new GridData();
data.horizontalSpan = 2;
lDescription.setLayoutData(data);
//Row two
Label lDollar = new Label(comp, SWT.WRAP | SWT.RIGHT);
lDollar.setText("$");
//This line has no effect on the widget at all.
lDollar.setSize(50, SWT.DEFAULT);
data = new GridData();
lDollar.setLayoutData(data);
Text _tAmount = new Text(comp, SWT.BORDER | SWT.SINGLE);
//Again, this line has no effect
_tAmount.setSize(60, SWT.DEFAULT);
data = new GridData();
_tAmount.setLayoutData(data);
//One more widget that spans two columns, and then another couple rows
//Return this Composite
return comp;
}
The dialog box won't be resized or anything, so I don't have a problem
with hardcoding width and height. Can anyone tell me how to set the size
of my widgets (since widget.setSize(width, height) doesn't work in this
case)? Or alternatively, could anyone tell me how to set the size of each
column?
Thank you,
Kevin

Hi, Kevin.
Don't use setSize() on the widget. Instead, set the widthHint/heightHint
fields of the GridData.

You try :
GridData data = new GridData();
data.widthHint = 50;
data.heightHint=20;
widget.setLayoutData(data);
