[Question] How to get QWidget background transperent

Hey got a big problem.

Googled now for 4 hours and tryed alot of idears...


My problem is that i want to draw over another application.

last thing whats missing is that only the background of the QWidget is transparent without the childs.


this->setWindowOpacity(0.25);

is "working" but it also makes all other things that i draw onto the frame transperent.


anyone got a way to resolv that problem?

Code:

---

QWidget::setStyleSheet("background-color: transparent;");

You can set the stylesheet to your widget.

Code:

---

// Set window color transparent and border to none
myWidget->setStyleSheet("background-color: transparent; border: none;");

---

CHEERS

hey thanks for your fast replay.

if i use: this->setStyleSheet("background-color: transparent; border: none;");

the Window is just completly black.


this is my code in constructor:

Code:

---

ui->setupUi(this);
    this->setStyleSheet("background-color: transparent; border: none;");
