Hi all,

I am new to Qtopia. I have managed to install qtopia-core-opensource-4.3.2 and I would like to know which QtDesigner I could use with this Qtopia.

Are there more then one designer?

Please don't cross post, one post per subject is enough.

QtDesigner is from Qt package, not from Qtopia.
After install Qt, you will get QtDesigner and Qvfb. The 2 are very helpful tools when you work on Qtopia.
There is a good document on www.youtiyou.com, talking about embedded linux and Qtopia.

Tnx for the replay! But I still don't know which version of QTDesigner I could use with Qtopia. If I understand right Qtopia does not have its own designer?

Benjamin, since you are not coding ON your embedded system, but on a PC, you can install the regular Qt on your PC and use the designer that comes with it.
Designer does nothing more than generate an ui file.
You can then put that file in your embedded app code.
In case QTopia does not use uic, you can first generate the code from the ui on your PC, and copy the generated code to your embedded project.

OK. I have tried to make some simple app (form with one button) with QtDesigner 3.3.6 but when I try to compile it, it says uic: File generated with too old version of Qt Designer.

My enviroment variables are:

Qt4 and Qt3 are not compatible.
Choose one of the two.
Qt3 designer allowed some basic application code, which was not really a good design in my view, and I guess the trolls see that also that way, since Qt4 designer does not allow code manipulation any more, just ui design.
If you are working with Qt3, I suggest you just create the ui with the designer, do the rest of the code normally.

I think the Qtopia article on http://www.linuxdevices.com/articles/AT7319394180.html may be helpful in this discussion.

This popular white paper is written by some engineering folks from our organization Mindfire Solutions (http://www.mindfiresolutions.com).

I hope you find it useful!

I have found out that I can not use QtDesigner3 with Qtopia. Based on the article that I read I can only use QtDesigner2 :-( What about QtDesigner4?

I used QDeisgner4 with Qtopia4.
