QDialogBox GUI makes a Framebuffer copy

[CptN3m0]

@jsulm can't check right now, how my application would work without this thread.
But mayber because I check if some button in my GUI was clicked or not?

if(ui->pB_B->isChecked() == true  || ui->pB_B_2->isChecked() == true){
 // some code
}

@CptN3m0 As long as you don't do this in your thread it shouldn't be a problem.

@jsulm well.. I'm doing this in my thread.. this is also the problem, because I'm checking the state of some GUI elements?

[jsulm]

@CptN3m0 You should not access any UI related classes from other threads than GUI thread. This is not supported.

@jsulm what should I do then, to get it working correct?

Hi,

Use signals and slots to communicate your UI values to the thread.

@SGaist Hi, can you show me a little example?

[SGaist]

Well, add two setters to your MyThread class, one for each boolean value that you want to check and connect them to your GUI.
