@jeremy_k Thankyou

QPixmap pixmap(QPixmap::fromImage(QImage(img.data, img.cols, img.rows, img.step, QImage::Format_RGB888)).copy()); if this does not work than your incoming image data is not correct. You can easily look what's inside the QImage by saving it to a file.

@Qt-User0307 How do you get this PIXMAP?Where does this PIXMAP`s source data come from and what kind of data is it?

@kayakaan02 As @J-Hilk has said, but you might use const char *QByteArray::constData() const for efficiency/safety, assuming you really want a const uint8_t*, since I imagine you will not be altering the data.

@Christian-Ehrlicher thanks, yes i checked ui, prolly i deleted the button by mistake.

@Chris-Kawa Thank you, You gave me a good hint and I think I solved the problem. As you wrote, the problem is related to unlinked SSL.

@prex said in [QMutexLocker in Q_PROPERTY READ/WRITE methods blocks execution](/post Is the datum underlying the property atomic, or otherwise guaranteed by the target platform guaranteed to be consistently accessed across threads? Using a mutex in one thread and not in the other doesn't appear to buy anything useful. Not sure if I understand. But both threads use the same mutex since they both call the getter/setter method. One over properties, one directly by calling the method. I wasn't sure if "directly accessing them" meant the getter and setter functions, or the datum. Since it's now clear that it refers to the functions, that implies access to the QObject instance. In that case, be aware that very few of QObject's functions are thread-safe.

@JonB Thanks for your response. I think I have a pretty good idea what I have to do now.

@mtty said in What can I do in my custom map plugin?: Now I wonder - how many features can I add to the map? Specifically, can I add layers? Can I modify how a map item (ie polygon) is drawn? Can I draw a grid? See here According to your grid question, see here

@Bonnie Great, thank you for your explanation, although I still find it weird that numRowsAffected() gives me the number of rows ...XD

@jaggusri12 A typical solution is just to constantly redraw with whatever the most recent frame is. Effectively a "pull" strategy, rather than "push."

Thanks for your help @mpergand , it's working!! :)

Have you found any solution to this problem? or what was causing the issue?

Have you found solution any solution to this problem?

@Captain-Haddock said in Hiding/unhiding parent dialogs affects mouse handling: I tried this and the hide/unhide works but a side effect appears to be that a mouse release handler on the window subsequently fails to trigger MouseRelease in what class? Side-note: Your "window" only gets the event, if no other child widget consumes it. Any mouseRelease on child widgets of your window doesnt trigger Window::mouseReleaseEvent. Events are propagated up the object tree until one widget takes it.

@JonB Your solution works. ...
