问题 I want a table cell with text aligned to the left and icon aligned to the right side. But now, im getting both icon and text left aligned, here what i have tried QtTableWidgetItem * item = new QtTableWidgetItem("program"); item -> setIcon(icon); ui -> tableWidget -> setItem(i,j,item); 回答1: To manage the position of the icon and the text you must use a delegate, in this case I use the QStyledItemDelegate and I overwrite the initStyleOption() method: C++ version aligndelegate.h #ifndef

问题 I'm fairly new to C++ in general, so I need a little help with Qt. I'm trying to add an image to a PushButton, and I keep having problems with it. Here is an example of what I have: #include <QtWidgets/QPushButton> QPushButton *button; button = new QPushButton(Example); button->setObjectName(QStringLiteral("button")); button->setGeometry(0,0,128,56); So I have a picture saved in /example/pics/example.png (example being the project name), and I would like to use it on the PushButton. I've been

问题 This question already has answers here : Issue when loading an ico from a Qt resource file (5 answers) Closed 8 months ago . I have a *.ico file. The icon is loaded by the setWindowIcon() function. I added a *.ico file to the resource file. When I launch the application from Qt Creator, the icon is displayed correctly. But when I launch the application from outside Qt Creator, the icon is not displayed. The application successfully starts and works, but the icon is not displayed. this-

问题 So let's say I do something like this: QIcon myIcon(":/resources/icon.ico"); How can I later determine the path for that icon, e.g. QString path = myIcon.getPath(); The problem is, there is no getPath() member, and I can't find anything similar, but surely there must be a way!

No XVisualInfo for format QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(),

问题 I am making a file browser in qt for some custom design-files. I want to load their preview as their thumbnail and for that reason I am using QIconProvider to return the Icon to my QFileSystemModel . The problem is that the algorithm that creates the QIcon needs some resources and as a result my application is not responsive until it finishes loading all the thumbnails. I am wondering if there is any way to put my QIconProvider in a background thread, so that I have my application responsive.
