Help with QDockWidget

[mindbender]

I'm sure this question has been answered somewhere in this forum but I can't seem to find exactly what I need so I'm going to ask you guys for a little help. I'm trying to build an app using the QDockWidget. My problem is getting things working properly. Let me start by asking, is it proper protocol to design my "QDockWidget" in designer or am I supposed to to design a std widget in designer and sub-class it as a QDockWidget? I've been trying to design my QDockWidget and then use it directly. (see code below). It just seems I'm making things more complicated than they should be in this IDE.

Pls note that I deleted some of what I thought to be non-essential code for brevity. If you need everything just ping me on skype or gmail and I'll send it over.

Thanks for you help!!!

Let me start by asking, is it proper protocol to design my "QDockWidget" in designer or am I supposed to to design a std widget in designer and sub-class it as a QDockWidget? I've been trying to design my QDockWidget and then use it directly. (see code below). It just seems I'm making things more complicated than they should be in this IDE.

It doesn't matter which way you use. You can use your main window ui and add the dock widget right there, or you can make a own class "dock widget" at the designer and add it the the main window by calling addDockWidget().
I personally like the last approach since it separates your code nicely. All the code belonging to the dock widget is bundled at one place.

(And we have nice [CODE] tags at this forum)

[mindbender]

My apologies, I didn't think about the code tags. Is it possible you or someone could post a simple example of what the code would look like
with a qdockwidget created in the designer coded into a main window. I've been fighting it for awhile and I'd like to see what i'm not doing right.

Thanks again! I'll be sure and use the code tags from now on too. :-)

[Lykurg]

Just a quick build...

[mindbender]

Thank You Lykurg for your kindness!

[mindbender]

Ah looks like my code was correct. The problem was that I had renamed the "DockWidget.ui" file to "criteriabuilder.ui" without changing the name of the class in QDesigner.
When I try to do anything with class "CriteriaBuilder" it did a lot of complaining. Once I found the naming issue in the UI file everthing was as you said it should be. I knew
I was somehow making things overly complicated.

...again I appreciate your help.

...again I appreciate your help.

You are welcome! Good you find that error.
