qgraphicsview

I've created something like this. I have created a QGraphicsPixmapItem object that I can add to QGraphicsView. I want to add ports to these objects I created. And I want to make connections between these ports and the objects I have created. I don't know how to do it. can you help me ? my code class Part(QGraphicsPixmapItem): def __init__(self, name): super().__init__() self.name = name self.setFlags(self.ItemIsSelectable | self.ItemIsMovable | self.ItemIsFocusable) self.label = QLabel("Deneme") self.pixmap = QPixmap("image/" + name + ".png") self.setPixmap(self.pixmap) self.inputs = {} self

I have a problem trying to paint and draw on QGraphicsView/Scene . I'm drawing a bunch of QLineF as background overriding QGraphicsView::drawBackGround`. However, when I try to change the background color nothing happens. Here is minimal example of what I'm doing: import sys import platform import ctypes from PySide import QtCore, QtGui from mygv import Ui_Dialog import sys class myView(QtGui.QDialog): def __init__(self, parent = None): QtGui.QDialog.__init__(self, parent) self.ui = Ui_Dialog() self.ui.setupUi(self) self.ui.view.drawBackground = self.drawBackground self.ui.view.wheelEvent =

I have a QGraphicsTextItem parented to a QGraphicsItem. I want the QGraphicsTextItem to always reside directly above the QGraphicsItem, but I also want the text to remain the same size when the scale factor goes below 1, i.e. the text remains the size it is at a scale factor of 1 even when the parent graphics item is scaled smaller. I have found that setting the QGraphicsItem::ItemIgnoresTransformations flag to true when the scale factor is below 1 does the trick for retaining the size. But I can’t seem to find a way to get the position of the text to always remain above the QGraphicsItem. Is

I have a scene like this class Scene(QtWidgets.QGraphicsScene): def __init__(self, parent=None): super(Scene, self).__init__(parent) def mousePressEvent(self, event): print('scene pressed') self.wid = MyRect(event.pos(), event.pos()) self.addItem(self.wid) self.wid.show() I would like class MyRect(QtWidgets.QGraphicsRectItem) with painter, mouse event and so on to be a draggable rectangle. all stuff in MyRect So then I could have many Rectangle to the scene and even after draw line between them and so on (kind of diagram app), but keeping objects related editable options in MyRect, MyLine , ..

I have added a widget to a graphic scene QGraphicScene through a QGraphicsProxyWidget. To move it I have set QGraphicsRectitem as its parent. The widget is resized with the use of a sizegrip. The first time I create an object I can enlarge it upto some dimension. The second time I can enlarge it less than the first one. The third time less than the second one and so on. It seems to me that it behaves randomly. Why is this happening? Here is the code: void GraphicsView::dropEvent(QDropEvent *event)// subclass of QGraphicsView { if(event->mimeData()->text() == "Dial") { auto *dial= new Dial; //
