QGraphicsSceneMouseEvent about qt

[therecipe]

These work for me now.

func mousePressEvent(e *widgets.QGraphicsSceneMouseEvent) {
    var color = gui.NewQColor2(160, 160, 160, 255) // r,g,b,a
    var pen = gui.NewQPen3(color)
    pen.SetWidth(1)
    var brush = gui.NewQBrush()

    scene.AddRect2(e.ScenePos().X(), e.ScenePos().Y(), 5, 10, pen, brush)
}

Or if you override the ConnectMousePressEvent on the QGraphicsView

func mousePressEvent(e *gui.QMouseEvent) {
    var color = gui.NewQColor2(160, 160, 160, 255) // r,g,b,a
    var pen = gui.NewQPen3(color)
    pen.SetWidth(1)
    var brush = gui.NewQBrush()

    var pointOnScene = view.MapToScene5(int(e.Pos().X()), int(e.Pos().Y()))
    scene.AddRect2(pointOnScene.X(), pointOnScene.Y(), 5, 10, pen, brush)
}

First example you gave:

    build
    output:# local/qt_test
    .\test1.go:178: cannot use e.ScreenPos().X() (type int) as type float64 in argument to scene.AddRect2
    .\test1.go:178: cannot use e.ScreenPos().Y() (type int) as type float64 in argument to scene.AddRect2

    error:exit status 2

Second example gives:

    build
    output:# local/qt_test
    .\test1.go:156: cannot use mousePressEvent (type func(*gui.QMouseEvent)) as type func(*widgets.QGraphicsSceneMouseEvent) in argument to scene.ConnectMousePressEvent

    error:exit status 2

If I use QGraphicsSceneMouseEvent instead, I get the same problem as before but in the opposite direction. Box lands top left from mouse pointer, before it landed bottom right by a few hundred pixels.

I think the Pos method is what I'm supposed to use but it's not there.

Hey

Sorry, you have to sync with the repo first.

Also the first example is slightly edited and now uses e.ScenePos().X() instead of e.ScreenPos().X()
And the second example needs to be used in view.ConnectMousePressEvent (QGraphicsView)

Hope it works now ;)

I see now. Even when I stare at something several times I miss it. Sorry. It's working now. Thanks!
