3/14/2023 0 Comments Mouse coordinates in qt![]() However when looking at the object from a point say along the x-axis, the model will move along the x-axis instead of following the mouse position. This works great when looking from a point that is on the same z-axis. The use case is that whenever the mouse is pressed while pointing at the cube, whenever the mouse moves it will cause the cube to move along with it to the corresponding point in the 3d Scene. SelectedItem.position = multiply_vectors(worldCoords, Qt.vector3d(Math.abs(camera.z - selectedItem.z), Math.abs(camera.z - selectedItem.z), 1.0)) In Qt coordinate systems (0,0) is upper left. Var worldCoords = view.mapTo3DScene(sceneCoords) 2 Answers Sorted by: 10 I am afraid, you won't be happy with your requirement 'lower left must be (0,0). ![]() Var sceneCoords = Qt.vector3d(viewCoords.x, viewCoords.y, 0) To associate a cursor with a widget, use QWidget. Qt has a number of standard cursor shapes, but you can also make custom cursor shapes based on a QBitmap, a mask and a hotspot. mouse click notification and mouse coordinates is I want to try to make simple buttons with a regular console program. Var viewCoords = view.mapFromGlobal(mouseArea.mapToGlobal(mouse.x, mouse.y)) This class is mainly used to create mouse cursors that are associated with particular widgets and to get and set the position of the mouse cursor. Var result = view.pick(mouse.x, mouse.y) I also made other tests, using QApplication and QDesktopWidget classes with no luck.Return Qt.vector3d(vec1.x * vec2.x, vec1.y * vec2.y, vec1.z * vec2.z) ĪcceptedButtons: Qt.LeftButton | Qt.RightButton I know that with libX11 it's possible, because I did it in the past, but I need to work with Qt 5, and I can't figure out how to do detect the selected screen with Qt. My idea, is to open/launch an application (executed by a Qt daemon that must detect the selected screen) to the screen where the mouse is. I don't know if that's a normal behavior or a bug, since the documentation doesn't say what happens when the screen argument isn't the screen where the mouse is. ![]() Since the both positions has the same values, I can't know at which screen is the cursor. But it's not the case, the both positions ( pos0 and pos1) has the exactly same value, as we can see on the output: screen0 DVI-D-0 What I was expecting, is that only one screen would return a valid position, since the cursor is only at one screen, not on both. ", screen1->name().toStdString().c_str()) If all you want to do is to report position of the mouse in coordinates as if the widgets lower-left corner was (0,0) and Y was ascending when going up. ![]() In this example, we display the x and y coordinates of a mouse pointer in a.

QScreen *screen1 = QApplication::screens().at(1) Not global, but hopefully the position within your application is. The best I can suggest is to use the Item::mapToItem () function to map to your. It contains a bitwise combination of: Qt.LeftButton. QMouseEvent conteins globalX and globalY. For mouse release events this excludes the button that caused the event. For mouse press and double click events this includes the button that caused the event. That's the code I used to make the test: QScreen *screen0 = QApplication::screens().at(0) For mouse move events, this is all buttons that are pressed down. I made some tests, and the results didn't work as I expected, so I decided to make a new post to talk about the test I made and to find an alternative solution. First of all, I'd like to mention that I found that related post How to get the mouse position on the screen in Qt? but it "just didn't work" for me.
