Popping up a dialog?

**brcain** · 24th February 2006, 02:10

I'm still learning the role that Qt Designer plays ... IDE-light or strictly UI shell generator. There is afterall a signals/slots editor.

How do you (in Designer) popup a dialog? For example, from a menu Help->About action?

Is this sort of thing done in Designer? Or does it have to be done in code?

Thanks,
Ben

Designer is only a layour editor.

You can't do this.

You must write some code.

Does the signal/slot editor sort of muddy the water a bit? That editor is modeling behavior. So, it seems that there is more than just layout going on.

Not trying to be difficult ... just tried to identify/rid my misconceptions.

Much Thanks,
Ben

You can create some typical connections using this editor or just ignore it. There is also action editor which saves you a lot of typing, but still main purpose of the Designer is to design layouts.

In Qt 3 Designer you could even edit code, but this additional functionality was more like a hack and luckily it was removed in Qt 4.

I do appreciate the desire to separate the "code" from the UI. I try to go a step further by leveraging the model-view-controller architecture. It seems to support the life-cylcle better.
