@Christian-Ehrlicher Hi, I have not manually set any css styling the colours I belive just come from fact I am using ubuntu so I think its just using system colours by default

@Saviz Sorry, I don't know such article. But basically create a settings object and store the settings in it instead of in widgets classes.

I added the following two lines of code and it worked:

QHBoxLayout *camera_layout = new QHBoxLayout(this); mCamera = new QCamera(); mCameraViewfinder = new QCameraViewfinder(); camera_layout->addWidget(mCameraViewfinder); mCamera->setViewfinder(mCameraViewfinder); mCamera->start();

And it worked

@Christian-Ehrlicher
Now I got it
It does not have size for the contents of window and
if we put layout to it then it will try to keep content inside it

It is shown in ui file
and because it has no content on given portion so it wont display anything

Thank You

@JJLee said in Pushbutton promoted from QPushButton is invisible:

it led me to the solution!

great! so please don't forget to mark your post as solved then.

@Mark81 Feel free to provide a patch :)

@mrjj @Ratzz Thank u guys alot for helping me fix this prob.

@Charby that would also be fun.
The biggest technical problem I see is that the location field in the account is just plain text, so no way of knowing what is in it. A more defined field would be needed.

I need some more hours in the day to investigate how much effort it would be.
