I’ve found the answer, after some digging. In Windows 7, the taskbar is not for “Application Windows” per se, it’s for “Application User Models”. For example, if you have several different instances of your application running, and each instance has its own icon, then they will all be grouped under a single taskbar icon. Windows … Read more
If a large amount of data is sent, the packet can arrive in separate parts. Alternatively, multiple messages can be received in one readyRead slot. It’s good practice to control this by setting the first byte(s) to the number of bytes that will be sent. Then, in readyRead, you read the first bytes and append … Read more
Use a QML Singleton. Please reference “Approach 2” on this page — The ugly QTBUG-34418 comments are mine. These are the pieces you need: Style.qml pragma Singleton import QtQuick 2.0 QtObject { property color mainbg: ‘red’ } qmldir This file must be in the same folder as the singleton .qml file (Style.qml in our example) … Read more
Here are the full instructions: Get it: git clone https://github.com/mxe/mxe.git Install build dependencies Build Qt 5 for Windows: cd mxe && make qtbase This will first build its dependencies and the cross-build tools; It should take less than an hour on a fast machine with decent internet access. Due to the new modular nature of … Read more
Based on @j3frea suggestion, here is a working example (using PySide). It appears that the model needs to be set every time splitPath is called (setting the proxy once in setModel doesn’t work). combobox.setEditable(True) combobox.setInsertPolicy(QComboBox.NoInsert) class CustomQCompleter(QCompleter): def __init__(self, parent=None): super(CustomQCompleter, self).__init__(parent) self.local_completion_prefix = “” self.source_model = None def setModel(self, model): self.source_model = model super(CustomQCompleter, … Read more
Deleting QObjects is usually safe (i.e. in normal practice; there might be pathological cases I am not aware of atm), if you follow two basic rules: Never delete an object in a slot or method that is called directly or indirectly by a (synchronous, connection type “direct”) signal from the object to be deleted. E.g. … Read more
You can use a qmake function for reusability: # Copies the given files to the destination directory defineTest(copyToDestdir) { files = $$1 for(FILE, files) { DDIR = $$DESTDIR # Replace slashes in paths with backslashes for Windows win32:FILE ~= s,/,\\,g win32:DDIR ~= s,/,\\,g QMAKE_POST_LINK += $$QMAKE_COPY $$quote($$FILE) $$quote($$DDIR) $$escape_expand(\\n\\t) } export(QMAKE_POST_LINK) } then use it … Read more
This answer is in a series of my overlay-related answers: first, second, third. One way of doing it is: Have a semi-transparent overlay widget that is also transparent to mouse events. In the event filter, track the clicks and the resizing of the objects by adjusting the overlay’s geometry to match that of the target … Read more
For my Qt project, I use this scheme in *.pro file: HEADERS += src/dialogs.h SOURCES += src/main.cpp \ src/dialogs.cpp Release:DESTDIR = release Release:OBJECTS_DIR = release/.obj Release:MOC_DIR = release/.moc Release:RCC_DIR = release/.rcc Release:UI_DIR = release/.ui Debug:DESTDIR = debug Debug:OBJECTS_DIR = debug/.obj Debug:MOC_DIR = debug/.moc Debug:RCC_DIR = debug/.rcc Debug:UI_DIR = debug/.ui It`s simple, but nice! 🙂
I had a similar problem and it was solved using jecjackal’s comment. As sjwarner said, it would be much more noticeable in the form of an answer. So I’ll provide it. For the benefit of any future viewers. Again, it isn’t my answer! Appreciate jecjackal for it! As it is said in the Qt’s stylesheets … Read more
