Simple GridLayout problem [message #448048] Wed, 29 December 2004 08:44 Go to next message

Hi

I wondered if somebody could help me with a simple layout problem using
grid layout. I would like to layout two rows. First row: label, text,
button. Second row label, text. I would like the text to take up all
horizontal space. I use the code posted below but the text widget of the
first row does not excess all the space. Instead the button column is too
wide. I do not see what I am doing wrong.
I could probably solve the problem using a different layout but I am
curious to know why my attempt does not work.


Group generalDataGroup = new Group(container, SWT.NONE);
layout = new GridLayout();
layout.numColumns = 3;
layout.verticalSpacing = 9;
layout.makeColumnsEqualWidth = false;
generalDataGroup.setLayout(layout);
gd = new GridData(GridData.FILL_HORIZONTAL);
gd.horizontalSpan=1;
generalDataGroup.setLayoutData(gd);


// first row
label = new Label(generalDataGroup, SWT.NONE);
label.setText("label1");

Text text = new Text(generalDataGroup, SWT.SINGLE|SWT.BORDER);
gd = new GridData(GridData.FILL_HORIZONTAL);
gd.grabExcessHorizontalSpace = true;
// if I use this hint everything looks fine:
//gd.widthHint = 400;
text.setLayoutData(gd);

Button button = new Button(generalDataGroup, SWT.PUSH);
button.setText("...");

// second row
label = new Label(generalDataGroup, SWT.NONE);
label.setText("label2");

text = new Text(generalDataGroup, SWT.SINGLE|SWT.BORDER);
gd = new GridData(GridData.FILL_HORIZONTAL);
gd.grabExcessHorizontalSpace = true;
gd.horizontalSpan = 2;
text.setLayoutData(gd);

Hi,

your code is good for the first look. Is it possible, to get an screenshot?
It would help, if you give your different Groups an Composites a
backgroundcolor.

But I've seen your code is very complicated. It will be easier for other to
understand your code, if you make it simpler like this.

Group generalDataGroup = new Group(container, SWT.NONE);
layout = new GridLayout(3, false);
layout.verticalSpacing = 9;
generalDataGroup.setLayout(layout);
generalDataGroup.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));

// first row
label = new Label(generalDataGroup, SWT.NONE);
label.setText("label1");

Text text = new Text(generalDataGroup, SWT.SINGLE|SWT.BORDER);
text.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));

Button button = new Button(generalDataGroup, SWT.PUSH);
button.setText("...");

// second row
label = new Label(generalDataGroup, SWT.NONE);
label.setText("label2");

text = new Text(generalDataGroup, SWT.SINGLE|SWT.BORDER);
GridData gd = new GridData(GridData.FILL_HORIZONTAL);
gd.horizontalSpan = 2;
text.setLayoutData(gd);

Bye Stefan

Hi,
after some discussion with Stefan it seems to me, that I ran into a bug in
the SWT. It seems to be solved already. After loading the latest SWT
package from CVS it works.
Thanx to Stefan.

Ciao, Thorsten
