I'm drawing a line between two widgets (two push buttons) into a graphics view with their positions as reference. But the line is drawn in a wrong place.
I tried using functions like mapToGlobal or mapToParent with different results, but it's still wrong. In the same class I have another method that draws lines with the mouse, and it works ok. I was taking it like a reference, but it seems that the events position has a different coordinate system. I don't know why this is happening.
The buttons and the graphics view are inside a Widget, which is also inside a window.
Here it is the class:
from PyQt4 import QtGui, QtCore
class WiringGraphicsView(QtGui.QGraphicsView):
def __init__(self, parent):
QtGui.QGraphicsView.__init__(self, parent)
self.setScene(QtGui.QGraphicsScene(self))
#self.setSceneRect(QtCore.QRectF(self.viewport().rect()))
def mousePressEvent(self, event):
self._start = event.pos()
def mouseReleaseEvent(self, event):
start = QtCore.QPointF(self.mapToScene(self._start))
end = QtCore.QPointF(self.mapToScene(event.pos()))
brush = QtGui.QBrush(QtGui.QColor(255, 0, 0) )
pen = QtGui.QPen(brush, 2)
line = QtGui.QGraphicsLineItem(QtCore.QLineF(start, end))
line.setPen(pen)
self.scene().addItem( line )
def paintWire(self, start_widget, end_widget):
start_position = QtCore.QPointF(self.mapToScene(start_widget.pos()))
end_position = QtCore.QPointF(self.mapToScene(end_widget.pos()))
brush = QtGui.QBrush(QtGui.QColor(255, 0, 0) )
pen = QtGui.QPen(brush, 2)
line = QtGui.QGraphicsLineItem(QtCore.QLineF(start_position, end_position))
line.setPen(pen)
self.scene().addItem( line )
UPDATE: At this point I've tried several things: Since the buttons were contained in a QWidget object, I take them out from there. I put them in a GroupBox instead. Also tried without containers. I don't get satisfactory results. Honestly I don't know how to do this properly considering that I'm using Qt designer and creating class files for "promoted" widgets (in this case is the GraphicsView) and set up some properties using the UpdateUi method in the main file
UPDATE 2: Here it is the file where the application is loaded:
from PyQt4.QtCore import *

Here is an example how to draw a line between two QWidgets in a QGraphicsScene. In principle it is straightforward. The rectangle of a widget can be accessed by QGraphicsProxyWidget.geometry() and is in scene coordinates. So one can draw a line based on that.
Example:
from PySide import QtGui, QtCore
app = QtGui.QApplication([])
scene = QtGui.QGraphicsScene()
# put a button into the scene and move it
button1 = QtGui.QPushButton('Button 1')
scene_button1 = scene.addWidget(button1)
r1 = scene_button1.geometry()
r1.moveTo(-100, -50)
scene_button1.setGeometry(r1)
# put another button into the scene
button2 = QtGui.QPushButton('Button 2')
scene_button2 = scene.addWidget(button2)
r2 = scene_button2.geometry()
# add a line between the centers of each rectangles
scene.addLine(r1.x() + r1.width() / 2, r1.y() + r1.height() / 2, r2.x() + r2.width() / 2, r2.y() + r2.height() / 2)
# view on the scene
view = QtGui.QGraphicsView(scene)
view.resize(300, 200)
view.show()
app.exec_()
And it looks like:
And now the whole with dragging because it is not that trivial. Not the QGraphicsProxyWidget but the original QWidget, seems to get the mouse move/pressed events. We simply emit a new signal (dragged) and connect it to a function that can move the button in the scene around (using the return of scene.addWidget, the QGraphicsProxyWidget which is also a QGraphicsItem). It also redraws the line between the two buttons so they stay connected.
from PySide import QtGui, QtCore
class DraggablePushButton(QtGui.QPushButton):
"""
Extension of QPushButton that emits a dragged signal (QPointF which is the delta in movement of the mouse) as
long as it is pressed.
"""
dragged = QtCore.Signal(QtCore.QPointF)
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
def mousePressEvent(self, event):
self.position = event.globalPos()
def mouseMoveEvent(self, event):
# will only by called if the mouse is also pressed
position_now = event.globalPos()
self.dragged.emit(position_now - self.position)
self.position = position_now
def move_scene_button1_and_redraw_line(drag):
# move the button1 by a certain delta position and change line connecting them with it
scene_button1.moveBy(drag.x(), drag.y())
r1 = scene_button1.geometry()
line_item.setLine(r1.x() + r1.width() / 2, r1.y() + r1.height() / 2, r2.x() + r2.width() / 2, r2.y() + r2.height() / 2)
app = QtGui.QApplication([])
# the graphicsscene
scene = QtGui.QGraphicsScene()
scene.setSceneRect(-150, -100, 300, 200)
# put a draggable button into the scene
button1 = DraggablePushButton('Button 1')
scene_button1 = scene.addWidget(button1)
scene_button1.setPos(-100, -50)
r1 = scene_button1.geometry()
# connect dragged events to move of scene button
button1.dragged.connect(move_scene_button1_and_redraw_line)
# put another still standing button into the scene
button2 = QtGui.QPushButton('Button 2')
scene_button2 = scene.addWidget(button2)
r2 = scene_button2.geometry()
# draw line between button1 and button2
line_item = scene.addLine(r1.x() + r1.width() / 2, r1.y() + r1.height() / 2, r2.x() + r2.width() / 2, r2.y() + r2.height() / 2)
# view on the scene
view = QtGui.QGraphicsView(scene)
view.resize(330, 220)
view.show()
app.exec_()
And it still looks like:

I am trying to use draggable QLabels for cropping an image. The basic idea of my code is segmenting characters in an image.
So, the user will first upload an image contains three characters to the program.
Then, he will specify the type of the plate, is it short or long by checking on the suitable checkbox. Based on the checkbox, three boxes (QLabels) with specific size will be shown to the user so he can drag each box on a character in the uploaded image. Once the user is finished placing the boxes on the characters, he can click on the Segment button to apply the cropping operation. The final result will be three images of the cropped characters.
I have done from the program interface and some functionality, However, I'm facing a problem with darg and cropping functions. I have tried different ways with dragging boxes (QLabels) but it's not working with me. I really don't know what's wrong in my code :(. I'm using python 3 and PyQt5.
This is my code:

I hope I can find someone who can help me with that.
Thanks in advance.
I believe you are a bit confused about how drag and drop works, but the most important thing is that you don't need "actual" drag and drop for what you want to achieve.
In this example I added the draggable boxes instead of the labels, and they are free to be moved within the image rectangle. I had to do some modifications to your original code, because it was a bit confusing and had some logic that simply didn't work.
class DraggableLabel(QLabel):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.setStyleSheet("border-color: rgb(238, 0, 0); border-width : 2.0px; border-style:inset; background: transparent;")
self.origin = None
def setLimits(self, rect):
self.limits = rect
def mousePressEvent(self, event):
if not self.origin:
# update the origin point, we'll need that later
self.origin = self.pos()
if event.button() == Qt.LeftButton:
self.mousePos = event.pos()
def mouseMoveEvent(self, event):
if event.buttons() == Qt.LeftButton:
# move the box
self.move(self.pos() + event.pos() - self.mousePos)
def mouseReleaseEvent(self, event):
if event.button() == Qt.LeftButton:
# if the box is not within the image boundaries, move it
# back to the original position
if not self.limits.contains(self.geometry()):
self.move(self.origin)

You cannot and should not modify the GUI directly from another thread, in your case QTableWidget and QTableWidgetItem are part of the GUI so the code: self.tableWidget.setItem(2, 2, QTableWidgetItem(cnt)) is incorrect. What should be done is to send the information to the main thread through elements that are thread-safe such as signals, QEvents, etc.
On the other hand PyQt recommends not modifying the class it generates but creating a widget and using the generated class as an interface(1).
Considering the above the solution is:

I am a qt noob and I am trying to build an application that needs to display the following:
a list of e-mail (which I am displaying in column 1 of a grid layout
with a QListWidget1 left list)
a list of passwords (which I display in column 2 of grid layout in a QListWidget2 middle list)
Now, I would like to display a list of button (1 for every element of the list) which is supposed to copy the password in the QListWidget2.
Should I just loop in column 3 and add a push button for every row? Or is there a better way of doing this? Is there an object that could help me by laying out the buttons already in line with the elements of my list, so that I can connect them easily with the value of every entry in the list (for copying them later)?
My code is the following:
from PySide import QtCore, QtGui
class Ui_Dialog(object):

If you want to add a button for each item in the list, you can use setItemWidget.
To get the buttons to align to the right, use a layout as in the demo script below:
class Window(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
self.list = QtGui.QListWidget(self)
layout = QtGui.QVBoxLayout(self)
layout.addWidget(self.list)
def addListItem(self, text):
item = QtGui.QListWidgetItem(text)
self.list.addItem(item)
widget = QtGui.QWidget(self.list)
button = QtGui.QToolButton(widget)
layout = QtGui.QHBoxLayout(widget)
layout.setContentsMargins(0, 0, 0, 0)
layout.addStretch()
layout.addWidget(button)
self.list.setItemWidget(item, widget)
button.clicked[()].connect(
lambda: self.handleButtonClicked(item))
def handleButtonClicked(self, item):
print(item.text())
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
window = Window()
for label in 'red blue green yellow purple'.split():
window.addListItem(label)
window.setGeometry(500, 300, 300, 200)
window.show()
sys.exit(app.exec_())

As I said in the comments, QScrollArea doesn't need manual QScrollBar. It will create when needed. I can't be sure what your problem is without seeing the 'not working' code, but my guess is the fixed sized items and their placement. You are probably putting things outside of the widgets margin or overlapping each other so that the inner widget does not grow appropriately.
Anyway, here is a minimal example that replicates your dialog (notice the scrollbar):
import sys
from PyQt4 import QtGui, QtCore
class MyDialog(QtGui.QDialog):
def __init__(self, parent=None):
super(MyDialog, self).__init__(parent)
scrolllayout = QtGui.QVBoxLayout()
scrollwidget = QtGui.QWidget()
scrollwidget.setLayout(scrolllayout)
scroll = QtGui.QScrollArea()
scroll.setWidgetResizable(True) # Set to make the inner widget resize with scroll area
scroll.setWidget(scrollwidget)
self.groupboxes = [] # Keep a reference to groupboxes for later use
for i in range(8): # 8 groupboxes with textedit in them
groupbox = QtGui.QGroupBox('%d' % i)
grouplayout = QtGui.QHBoxLayout()
grouptext = QtGui.QTextEdit()
grouplayout.addWidget(grouptext)
groupbox.setLayout(grouplayout)
scrolllayout.addWidget(groupbox)
self.groupboxes.append(groupbox)
self.buttonbox = QtGui.QDialogButtonBox()
self.buttonbox.setOrientation(QtCore.Qt.Vertical)
self.buttonbox.setStandardButtons(QtGui.QDialogButtonBox.Cancel|QtGui.QDialogButtonBox.Ok)
layout = QtGui.QHBoxLayout()
layout.addWidget(scroll)
layout.addWidget(self.buttonbox)
self.setLayout(layout)
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
dialog = MyDialog()
dialog.show()
sys.exit(app.exec_())
