Why qt creator stops to update the header file for the UI?

dmmzy

I don't why but it seems that my qt creator stops to update the header file for the ui when I add some one element in the UI edit window of the qt creator.

It's like: I create a UI called userwindow in the UI design window. QT creator generates the two files for me:
userwindow.ui
ui_userwindow.h
Everything worked fine, but now, when I add some elements in the userwindow, I use @ui->@ to locate those elements,but I failed.

So now, in my qt creator design window, the UIs are all right. However, I can't locate the new-added element and therefore cannot operate them.

Any one has similar experience? Or is there any method to ask qt creator to update the ui_userwindow.h file??

Many thanks.

After you add new elements to your user interface rebuild / run you application, and after that you should be able to see your stuff.

Normally saving the ui file should be enough.

Do you have other projects open in Qt Creator? There could be some interference with other ui files?

Thanks for the help.

I tried rebuild and run, but it does not work.

I only open one project. Though, i did open several qt creators to edit a same project at the same time.
But now, I only open one creator and one project, it still does not work.--

i found something in the compile output:
@make: Leaving directory `/home/sz/Programming/codes/EC-build-desktop'
make: *** [userwindow.o] Error 1
The process "/usr/bin/make" exited with code 2.
Error while building project EC (target: Desktop)

it seems the make cannot generate the userwindow.o.

The above compile error is just because the h_userwindow.ui doesnot add the elements to the header file.

That's weird, you could maybe try « Rebuild all » and paste the whole compilation log.

At least we'll see if uic is correctly invoked.

I think this issue probably derives from that I defined another class in the userwindow.h.

I try to move the definition of that class behind the definition of the userwindow class and rebuild the project, it still does not work.

Sorry, you just cut the actual error message.

You must not change the ui_xxx.h files manually, as they are regenerated by uic for certain reasons.

If you move out your own class definition into another header file, make sure you

#include that file where you included the ui_xxx.h file
have "include guards":http://en.wikipedia.org/wiki/Include_guard in that file and make sure they are different from the other one!
