a SWT control refuses to "grab excess vertical space"
The case is that the TopTaskGroup(left one) can "grab excess vertical space" while resizing window
createAddBtnOnGroup
method), it doesn't grow as you resize the window. Why is that?
(I have a shell instance with 2-column GridLayout)
Code is here:
private void createTaskWidgets() {
createTopTaskGroup();
createNewTaskGroup();
}
private void createTopTaskGroup() {
Group topTa开发者_如何学PythonsksGroup = new Group(shell, SWT.SHADOW_NONE);
topTasksGroup.setText(TaskConsts.TOP_TASK_LIST);
topTasksTable = new TaskTable(topTasksGroup, TaskTable.SORT_BY_VOTES, iteration, this);
topTasksTable.setLayoutData(getTableGridData() );
topTasksGroup.setLayout(new GridLayout() );
topTasksGroup.setLayoutData(getTableGridData() );
topTasksGroup.pack();
}
private void createNewTaskGroup() {
Group newTasksGroup = new Group(shell, SWT.SHADOW_NONE);
newTasksGroup.setText(TaskConsts.NEW_TASK_LIST);
newTasksTable = new TaskTable(newTasksGroup, TaskTable.SORT_BY_CREATION_TIME, iteration, this);
topTasksTable.setLayoutData(getTableGridData() );
ToolBar actionToolBar = createAddBtnOnGroup(newTasksGroup);
newTasksGroup.setLayout(new GridLayout() );
newTasksGroup.setLayoutData(getTableGridData() );
newTasksGroup.layout();
newTasksGroup.pack();
// set actionToolBar's location to newTasksGroup's right-top position
actionToolBar.setLocation(
newTasksGroup.getLocation().x + newTasksGroup.getSize().x
- actionToolBar.getSize().x - 5,
newTasksGroup.getLocation().y - 2);
}
private GridData getTableGridData() {
GridData gridData = new GridData(0, SWT.FILL, false, true);
return gridData;
}
private ToolBar createAddBtnOnGroup(Group newTasksGroup) {
ToolBar actionToolBar = new ToolBar(newTasksGroup, SWT.HORIZONTAL | SWT.RIGHT);
addTaskToolItem = new ToolItem(actionToolBar, SWT.PUSH | SWT.RIGHT);
addTaskToolItem.setImage(new Image(display, TaskConsts.ICON_PLUS));
final MainWindow mainWindow = this;
addTaskToolItem.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
new CreateTask(getShell(), mainWindow);
}
});
GridData gridData = new GridData();
gridData.exclude = true;
actionToolBar.setLayoutData(gridData);
actionToolBar.pack();
return actionToolBar;
}
private void organize() {
GridLayout gridLayout = new GridLayout(2, false);
shell.setLayout(gridLayout);
shell.pack();
}
Thanks in advance~
Thanks for your excellent problem description!
It seems to me that this is a simple copy-paste bug.
The fourth line in your createNewTaskGroup method should not be
topTasksTable.setLayoutData(getTableGridData() );
but
newTasksTable.setLayoutData(getTableGridData() );
