qwidget

问题 We have a Qt based browser application which uses QWebEninge under the hood. Currently we are fighting with an issue where the screen goes blank for a moment eacht time the window gets or looses the focus (f.ex. each time the QVirtualKeyboard becomes invoked). Following a Qt's recommendation, we tried to implement QWindowsWindowFunctions::setHasBorderInFullScreen prior to call of QMainWindow::showFullScreen() . But this results in an inacceptable reduction of the available window area, e.g.

问题 [Update on 19 aug 2019 about workaround of this bug] environements: System: Windows 7 (reproduced on windows 10 PC on execution too) QT version: 5.11.2 as well as 5.13 compilation kit: Qt 5.11.3 MinGw 32bits ( mingw53_32 ) I encounter an issue with QDialog in Qt app. it's easy to reproduce, with multiple monitors(eg. 2 screens), you launch your application, then you move your main windows from one monitor to another one, then you click on the button of app to show a child dialog, then it this

问题 I am having some issue with layout in pyqt. After closing the items from the layout still if layout.count() returns the old item count. So I think .close() not really removing items from the layout. Here is a full working example. import sys from PyQt4 import QtGui,QtCore class LayoutTest(QtGui.QWidget): def __init__(self): super(LayoutTest, self).__init__() self.vvbox = QtGui.QVBoxLayout() self.dvbox = QtGui.QVBoxLayout() vbox = QtGui.QVBoxLayout() vbox.addLayout(self.vvbox) vbox.addLayout

问题 I can't figure it. I want to be able to swap out QWidgets according to events like button clicks but I am missing something and I haven't been able to search out any example along the lines of the code below. What I want to do is click one of the top buttons and get the widget below to switch between either the QCalendar or QtextEdit. Where am I going wrong? Thanks! #!/usr/bin/python import sys from PySide import QtGui, QtCore class Example(QtGui.QWidget): def __init__(self): super(Example,

问题 I have two classes named info and i2 in qt. info is a c++ class and i2 is a Qt designer from class . I want to use i2 as an environment for testing my info class. I included info.h in the header of i2.my info class has two constructor like below: info(); info(const void *ip, const char* pw, const void *hostName); now I want to make an object of info in i2 class and pass those three parameters( ip and pw and hostname) to info and use them in my program. like below: private: Ui::i2 *ui; info

问题 I'm trying to accomplish the following with a Qt (C++) app, cross OS. Upon running the program a new window pops up, a fullscreen QWidget. Now I want this to be see-through/transparent, so the user won't actually see it. On this 'layer' a user can drag his/her mouse to draw a (red) rectangle to select an area which is - when the mouse is released - taken a screenshot of. The problem: The issue lays in the whole transparent layer thing since this doesn't appear to work well cross OS. Because
