Qt Application .exe fails to open properly

brettspark

I am new to Qt, and I am having issues getting a .exe to open properly. Simply put, program opens but only displays a white window with the proper window name.
I'll first explain everything I did and attempt to be thorough.

1 Installed Qt from the offline installer: QtSdk-offline-win-x86-v1_2_1.exe (I have an x64 machine, didn't see a downloader for it)

Went through tutorial: Creating a Qt Quick Application (Transitions)
End program ran fine in Qt using Run command

2 Attempted to Open .exe in Debug Folder

Warning about DLLs required
Copied required DLLs one at a time as asked upon each successive open (looped through this step a bit)

3 Attempted to Open .exe in Debug Folder Again (post DLL-copying)

Window labelled Transition opens
Only consists of while box, nothing like what shows up during run command

4 Used Dependency Walker to verify DLLs

Said that IEShims.dll was also required, so I copied that into the folder as well

5 Still stuck with the white window

Any help would be greatly appreciated!

Thanks,
Brett Sparkman

Edit: Made it more readable. Spaces with newlines didn't work right, and I failed to preview before. The order I ran things in is top-down. Please forgive the poor numbering as well; I don't post on forums very often.

Hello,
What are debug console output messages (if any)? It may be you have an error in your QML files.

mine wouldnt work when I tried the other day but I have not completely finished my program so I decided not to worry about it yet and I had removed the .dll files from my folder. After I saw this and commented it on I decided to try again and I got the same errors as before about the .dll and one by one, just like you said, I copied in the required .dll files, to the debug folder. Once I had all that it needed I tried opening it again and it worked. I didn't do anything differnt that I know of unless some change I made to the program recently somehow effected it.

I know this doesn't really help you much but I figured I would share.

Thanks for the posts. I tried re-copying the .dlls again, and it still didn't work. I also tried using release mode (had to change from the *d*.dlls to the *.dlls), and that didn't solve the issue either.

As far as outputs messages go:

Application Output: Starting C:*\Qt\Transistion-build-desktop-Qt_4_8_1_for_Desktop_-_MinGW__Qt_SDK__Debug\debug\Transistion.exe...

These seemed normal to me, but I don't have very much experience.

Thanks,
