What do you mean by yourself ? Using the designer integrated with QtCreator ?

[hema]

Really strange...

Could you try to run the Calculator builder example ? To see if it also has the same problem

[hema]

I have tried calculator builder and text finder examples they are working fine

[SGaist]

Then copy the ui file from the example in your project and try to load to see if it works also there

[SGaist]

Then can you post your pro file and a minimal code example that reproduce the problem ?
