improper scaling of Qt Desktop application in windows 10

由 为君一笑 提交于 2019-12-21 12:13:49
问题 I'm writing a simple Qt (Widgets) Gui application for windows 10. I'm using the 5.6.0 beta version of Qt. The problem I'm having is that it isn't scaling right to the screen of my surfacebook at all: It's a bit hard to tell because SO scales the image, but notice how small the dock widget title bar controls are relative to the window title bar controls. This link from Qt talks about scaling, but it's mostly focuses on qml/qtQuick and mobile applications in general, and additionally seems to

Virtual keyboard or onscreen keyboard for QtWidgets applications?

由 戏子无情 提交于 2019-12-13 04:26:58
问题 I'm going to deploy the qtvirtualkeyboard in my widget-based application like so: #include <QtWidgets> int main(int argc, char *argv[]) { qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard")); QApplication app(argc, argv); QMainWindow window; QLineEdit input(&window); input.move(250, 250); window.show(); return app.exec(); } But the only issue is that the virtual keyboard input panel hides the underlying widgets and cover them! How should I achieve this? Is there any document or solution

How to dock a QDockWidgets inside a QSplitter?

由 元气小坏坏 提交于 2019-12-11 15:28:36
问题 I am trying to have a QSplitter accept QDockWidgets in my application. So far, I have done everything through the Qt Designer and what I have done is create three individual QWidgets. I then select all three of the QWidgets and I right click on them and select Layout->Lay out Vertically in a Splitter. This lays all three of the widgets in a splitter quite nicely. I then drag a Dock Widget to the Object/Class Window in the top right and set them in the Splitters Widget. This places the

问题 My knowledge of Python is still pretty basic, and I am only now trying to wrap my head around how to use / call libraries from within Maya. (Because I need to create a basic UI from QT Designer and have it be opened in Maya after converting it to a .py file) After I learned to properly convert a .ui to a .py, I now get this error in Maya "Module use of python34.dll conflicts with this version of Python" I tried following what was said here and here, but even then - after setting these
