[Interest] [interest] UITools - how to modify the GUI?

[Tamás Nagy]

Hi,

Ok, I added the mainwindow.ui to a resource file, now it can be opened.

With your solution it works and finds the tabs:

if (!file.open(QIODevice::ReadOnly | QIODevice::Text));

But I also have to modify the GUI, so I have to set it ReadWrite:

if (!file.open(QIODevice::ReadWrite | QIODevice::Text))

With this I get "Unknown Error" for trying to open the file.
I checked the file: it is not read only.
