I Everyone,

I'm trying to build a Wizard but i'm having problems with the wright
Layout and the Label warping. I want to Show a Label in an Groupbox the
wraps around when it reaches the end of the GroupBox. Now it only gets cut
if it reches the end and the text is not wraped.

Here is my code.

Group g1=new Group(composite, SWT.NONE);
g1.setLayout(new RowLayout(SWT.VERTICAL));
g1.setLayoutData(new RowData(300,120));
g1.setText("Bla");
g1.setSize(300,150);
Label l1= new Label(g1, SWT.WRAP);
l1.setText("~ Some long text ~");
l1.setSize(300,120);
g1.pack();

It would be nice if anybody could point out my error.

Thanks in advance
Chris

Hi Chris,

Setting a RowData-Object on the label should solve your wrapping problem:

public class LabelWrapping {
LabelWrapping() {
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new RowLayout(SWT.VERTICAL));

int width = 300, height = 150;

Group g1 = new Group(shell, SWT.NONE);
RowLayout rowLayout = new RowLayout(SWT.VERTICAL);
g1.setLayout(rowLayout);
g1.setLayoutData(new RowData(width, height));
g1.setText("Bla");

Label l1 = new Label(g1, SWT.WRAP);
l1.setLayoutData(new RowData(width - (rowLayout.marginLeft +
rowLayout.marginRight), SWT.DEFAULT));
l1.setText("~ Some long text ~ ~ Some long text ~ ~ Some long text ~ ~
Some long text ~ ~ Some long text ~ ~ Some long text ~");

shell.setSize(350, 250);
shell.open();

while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}

public static void main(String[] args) {
new LabelWrapping();
}
}

hth,

Remo
