qsettings

问题 I have a Qt program and currently I use the Qsettings.saveGeometry() and Qsettings.saveState() functions to allow the program to restore the layout that the user set in the previous session. However not all geometry is saved, only the main window and not the children especially floating position of docked windows and table column widths within docked windows. This thread seems to attempt to provide an answer (but in C++ and not python): http://www.qtforum.org/article/38362/save-geometry-of

问题 This question already has an answer here : QSettings::IniFormat values with “,” returned as QStringList (1 answer) Closed 5 years ago . In my QT project I am reading values from .ini file using QSettings. If the value contains comma character QSettings is not able to read it. How should I read such values? 回答1: Comma character is treated as list separator by QSettings . INI values with commas are parsed as string lists. You can convert a string list back to original string as follows:

问题 I am trying to save the geometry of a pop-up dialog-box and then restore it back whenever I call the pop-up dialog box (while the application is still running). But I couldn't figure it out. The code runs without error. But the window of the pop-up keeps changing it position vertically everytime it is open. Unless I close the whole application and then re-opened it again, the pop-up never goes to its original position in the center of the screen. I am trying to use QcloseEvent , QSettings and

问题 I am writing and reading string and int values using a file-backed QSettings object. When I later try to read the values from a different process, the values are read as strings instead of int. This is the code I am using to write values: QSettings settings("TestQSettings.ini", QSettings::IniFormat); settings.setValue("AAA",QString("111")); settings.setValue("BBB",222); This is the file created: [General] AAA=111 BBB=222 This is the code I am using to read values: QVariant qvar = settings

问题 According to Qt's docs for the latest Qt version, looking at QSettings, they say that system scope of settings on a Mac are stored in a directory /etc/xdg. Unfortunately, I'm not finding this to be the case on Mac OSX 10.10 Yosemite. Where do they store these settings? I mean, I've gotten QSettings to work in this example, but no /etc/xdg folder is to be found even when I do sudo su and assume root on my Mac in order to access that folder. 回答1: On a MacOS, $HOME/Library/Preferences/ should be
