make Custom QWidget selectable

Question

I'm working on a boardgame and I'm trying to make QWidgets (Rectangles) selectable. So I have a BoardView (inherited from QWidget) which contains BuildingViews, PlantationViews (both inherited from QWidget). It all shows up on the window, but it is not clickable. How can I make this clickable?

You could try to make a QMouseEvent implementation where the widget ID is forwarded, something like this:

In the implementation of your widget (e.g. YourWidget.cpp):

YourWidget::MouseReleaseEvent(QMouseEvent *event)
{
     emit clickedWithMouse(this);    // this is a signal, declared in YourWidget.h
}

In the "main" game file (e.g. Game.cpp):

Game::onButtonClicked(YourWidget* widget)    // this is a public slot, you must connect all YourWidgets's clickedWithMouse signals to this slot (in Game object code, e.g. when initialising the board)
{
    lastWidget = widget; //save the widget "ID" (lastWidget is a member of class Game)
    someFunction(widget); //do something with the widget (if you wish)
}
