I have a Composite that I want to be able to enable/disable programatically. The Control.setEnabled(boolean enabled) method works fine, but it does not give any visual information that the widget(s) are disabled.
What I would like to do is to have the disabled state mean the widgets are greyed out. Right now they just enter a weird state where the user is unable to click or perform any action on them.
Answer
The problem was indeed that I was disabling the composite and not the controls inside it. What I ended up doing was something like this:
public void recursiveSetEnabled(Control ctrl, boolean enabled) {
if (ctrl instanceof Composite) {
Composite comp = (Composite) ctrl;
for (Control c : comp.getChildren())
recursiveSetEnabled(c, enabled);
} else {
ctrl.setEnabled(enabled);
}
}
