Hello,
I am creating my own LaunchGonfigurationTab. Initially the method createControl is called by the Eclipse Framework if you extend a class from AbstractLaunchConfigurationTab.
The problem is that nothing of the components I add to the composite are displayed:
public void createControl(Composite parent) {
parent.setLayout(new RowLayout(SWT.HORIZONTAL));
parent.getLayout();
Composite comp = new Composite(parent, SWT.NONE);
//-Project-Group
Group lProjectGroup = new Group(comp,SWT.NONE);
lProjectGroup.setText("Project Properties");
RowLayout lGroupRowLayout = new RowLayout(SWT.HORIZONTAL);
lProjectGroup.setLayout(lGroupRowLayout);
GridLayout lProjectGroupLayout = new GridLayout(3, false);
lProjectGroup.setLayout(lProjectGroupLayout);
//ProjectLabel
Label lProjectText = new Label(lProjectGroup, SWT.NONE);
lProjectText.setText("Project:");
//Project-Goup Textfield
GridData lProjectGrid = new GridData(GridData.FILL_HORIZONTAL);
lProjectGrid.widthHint = 500;
mProjectTextfield = new Text(lProjectGroup, SWT.BORDER);
mProjectTextfield.setLayoutData(lProjectGrid);
mProjectTextfield.addModifyListener(new ModifyListener() {
public void modifyText(ModifyEvent e) {
updateLaunchConfigurationDialog();
}
});
....
}
I would appreciate any help..
Thanks and best regards
Alex

Hello, first: Thanks for your answer!
Okay I solved the problem with the layout for now, but there is still one problem left:
I want not the standard size so I resize the parent shell. Problem is that all components are only visible after resizing the window?!
I really don't know why and tried everthing like parent.getShell().layout()/update() e.c.
Here is some code:
protected Control createContents(Composite parent) {
parent.getShell().setSize(999, 999);
mComp = new Composite(parent, SWT.NONE);
mComp.setFont(parent.getFont());
mComp.setLayout(new GridLayout());
mComp.setLayoutData(new RowData());
//Preference Group
Group lPreferenceGroup = new Group(mComp,SWT.NONE);
lPreferenceGroup.setText("Preferences");
GridData lPreferenceGridData = new GridData();
lPreferenceGridData.horizontalAlignment = GridData.FILL;
lPreferenceGridData.grabExcessHorizontalSpace = true;
lPreferenceGroup.setLayoutData(lPreferenceGridData);
GridLayout lPreferenceGridLayout = new GridLayout(3, false);
lPreferenceGroup.setLayout(lPreferenceGridLayout);
//Location Label
Label lGeneratorMainFile = new Label(lPreferenceGroup, SWT.NONE);
lGeneratorMainFile.setText("Java Generator Location: ");
//Location Textfield layout
GridData lGeneratorLocationTextGridData = new GridData();
lGeneratorLocationTextGridData.horizontalAlignment = GridData.FILL;
lGeneratorLocationTextGridData.grabExcessHorizontalSpace = true;
//Location textfield
mGeneratorLocationText = new Text(lPreferenceGroup, SWT.BORDER);
mGeneratorLocationText.setLayoutData(lGeneratorLocationTextG ridData);
...
}
I would appreciate any help.
Best regards,
Alex

Moving your "parent.getShell().setSize(999, 999);" to the end of your
createContents(...) implementation will probably fix this.

The eclipse.platform newsgroup is probably a better place for this question.
It doesn't really have anything to do with swt.
