I've never used deferred commands before and your solution does sound
better. If I were to do what you said is this what the code would somewhat
look like (below)?
public class CallingClass {
private Command yesCommand;
private Command noCommand;
public CallingClass() {
yesCommand new Command() {
public void execute() {
yesButtonAction();
}
};
panel.Add(new AlertClass(yesCommand));
}
public void yesButtonAction() {
// Do yes button action here
}
public void noButtonAction() {
// Do no button action here
}
}
public class AlertClass extends Composite {
private Command yesCommand;
private Command noCommand;
private final Button yesButton;
private final Button noButton;
public AlertClass(Command yesCommand, Command noCommand) {
this.yesCommand = yesCommand;
this.noCommand = noCommand;
......
yesButton = new Button("Yes",new ClickListener(){
public void onClick(Widget sender) {
DeferredCommand.add(yesCommand);
}
});
noButton = new Button("No",new ClickListener(){
public void onClick(Widget sender) {
DeferredCommand.add(noCommand);
}
});
initWidget(...);
}
}
