swt buttons wont right-align

[Mark Reyes]

Hi All,

Good Day..

I need to create a dialog box for user to enter their name and implemented gridlayout.

I divide the shell widget into 3 columns and I want the first column be occupied by the label having it left aligned. Then I merge the last two columns and wanted the two buttons place right aligned into the shell.

But my problem is, the GUI does not draws itself correctly. Here's my code.

 public void createGUI()
{
Display display = new Display();
Shell shell = new Shell(display);
shell.setText("Project1");

GridLayout layout = new GridLayout();
layout.numColumns = 3;
layout.makeColumnsEqualWidth = true;
layout.verticalSpacing = 20;
shell.setLayout(layout);

GridData gridData = new GridData(GridData.FILL_BOTH);
Label label = new Label(shell, SWT.NONE);
label.setText("Please Enter Your Name:");
label.setLayoutData(gridData);

Composite composite = new Composite(shell, SWT.NONE);
gridData = new GridData(GridData.FILL_BOTH);
gridData.horizontalSpan = 2;
composite.setLayoutData(gridData);

layout = new GridLayout();
layout.numColumns = 1;
composite.setLayout(layout);

/**** Added  to make it fit
Label lblHidden = new Label(composite, SWT.NONE);
gridData = new GridData(GridData.FILL_BOTH);
gridData.heightHint = 1;
lblHidden.setLayoutData(gridData);
lblHidden.setVisible(false);*****/

gridData= new GridData(GridData.HORIZONTAL_ALIGN_END);
Button cmdOK = new Button(composite, SWT.PUSH);
gridData.widthHint =50;
cmdOK.setLayoutData(gridData);
cmdOK.setText("Ok");

Button cmdCancel  = new Button(composite, SWT.PUSH);
gridData= new GridData(GridData.HORIZONTAL_ALIGN_END);
gridData.widthHint =50;
cmdCancel.setLayoutData(gridData);
cmdCancel.setText("Cancel");

gridData = new GridData(GridData.FILL_BOTH);
gridData.heightHint = 15;
gridData.horizontalSpan = 3;
Text txtInput = new Text(shell, SWT.BORDER);
txtInput.setLayoutData(gridData);

shell.pack();
shell.open();

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

I want the two button cmdOK and cmdCancel be right align and in level with the label.

I can't seem to have the GUI drawn as what I wanted it to look so I added a label,lblHidden in this case, set its visible property to false and occupied the last two columns. That did the trick and the button right aligned themselves correctly.

I really wanted to know why this is so and appreciate any suggestions or maybe I just miss something in my code. I hope I had explain thing clearly.. Thanks.
