Hey guys, I'm just having a weird problem when I try to change qlabels focus with the keyboard. My problem is, I have 4 qlabels like a gridlayout with 2 columns and 2 rows. Since my application doesn't have a touchscreen display I had to override the keyPressEvent to manipulate the keyboard events. The problem is, when any directional key to change the selected label it doesn't rerender it, but if I press another key, the label just rerender as I want! I just debugged it and the label got the focus, but don't rerender the image. That's my code:

PS: I'll do some code refactoring on the code, I just did that do make easier(or not) to see what's the problem.

Qt Code: 
  1. //Refact THIS!!! 
  2. void MenuWindow::keyPressEvent(QKeyEvent *event){
  3.     if(event->key() == Qt::Key_Escape){
  4.         back->setFocus();
  5.         return;
  6.     }
  7.  
  8.     if(configLabel->hasFocus()){
  9.         //REFATORAR. EXTRACT METHOD
  10.         cout << "CONFIG LABEL COM FOCO!" << endl;
  11.         configLabelImage->load(STRING_PATH_TO_IMAGES+"icone_configuracoes_selected.png");
  12.         if(event->key() == Qt::Key_Down){
  13.             configLabelImage->load(STRING_PATH_TO_IMAGES+"icone_configuracoes.png");
  14.             storageLabel->setFocus();
  15.         }else if(event->key() == Qt::Key_Right){
  16.             configLabelImage->load(STRING_PATH_TO_IMAGES+"icone_configuracoes.png");
  17.             multimediaLabel->setFocus();
  18.         }
  19.         configLabel->setPixmap(QPixmap::fromImage(*configLabelImage));
  20.     }else if(multimediaLabel->hasFocus()){
  21.         cout << "MULTI LABEL COM FOCO!" << endl;
  22.         multimediaLabelImage->load(STRING_PATH_TO_IMAGES+"icone_multimedia_selected.png");
  23.         if(event->key() == Qt::Key_Down){
  24.             multimediaLabelImage->load(STRING_PATH_TO_IMAGES+"icone_multimedia.png");
  25.             energyLabel->setFocus();
  26.         }else if(event->key() == Qt::Key_Left){
