I guess you can use setItemDelegate method of the treeview to setup custom painter for your treeview items. In the delegate’s paint method you can use QTextDocument to load item’s text as html and render it. Please check if an example below would work for you: treeview initialization: … // create simple model for a … Read more
QProcess process; process.start(“gedit”, QStringList() << docPath); the same as above QProcess process; process.start(“gedit”, QStringList() << “/home/oDx/Documents/a.txt”); Also, read this.
Both are build systems, but they’re not very similar at all. If your project uses Qt, you’re probably best off using qmake. CMake is more generic, and fits pretty much any type of project. Both qmake and CMake generate a Makefile, which is read by make to build the project. Not all build systems generate … Read more
Generally, usage of implicitHeight/Width only makes sense within reusable components. It gives a hint, of the natural size of the Item without enforcing this size. Let’s take a Image as an example. The natural size of the image would map one pixel from the image file to one pixel on the screen. But it allows … Read more
In addition to Troubadour’s comment, I would note that the SUBDIRS target is only good for specifying subdirectories. Therefore, your extra line of SOURCES += main.cpp in your project.pro file is incorrect, and will likely fail to build your main.cpp file, at worst. At best, qmake will refuse to parse the file, since it has … Read more
For historic reasons, mostly. Exception support in compilers took quite some time to mature. Citing Nokia’s Tobias Hunger: “When Qt was started exceptions were not available for all the compilers that needed to be supported by Qt. Today we are trying to keep the APIs consistent, so modules that have a history of not using … Read more
You can use the style hint property of QFont: QFont font(“Monospace”); font.setStyleHint(QFont::TypeWriter); If the font cannot be found (which happens with Monospace on Windows), Qt’s font matching algorithm tries to find a font that matches the given style hint.
Insert into the QTableWidget following kind of items: QTableWidgetItem *item = new QTableWidgetItem(); item->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled); Works fine! EDIT: QTableWidgetItem *item = new QTableWidgetItem(); item->setFlags(item->flags() ^ Qt::ItemIsEditable); This is a better solution. Thanks to @priomsrb.
You can try this one: QString QFileDialog::getExistingDirectory ( QWidget * parent = 0, const QString & caption = QString(), const QString & dir = QString(), Options options = ShowDirsOnly ) [static] This one is used to choose a directory, and will popup a dialog like you show at last. Demo: QString dir = QFileDialog::getExistingDirectory(this, tr(“Open … Read more
The compile error you get is because you try to pass a QSizePolicy::Policy to setSizePolicy(QSizePolicy), but there’s no implicit conversion from QSizePolicy::Policy (which is the policy for one dimension) to QSizePolicy (which is a class containing, among other things, one Policy per dimension (height, width)). QSizePolicy doesn’t work on top-level widgets (windows) anyway, though. setFixedSize() … Read more
