qt5

问题 As I would like to build my Windows version of Qt5 application (C++) statically, I downloaded the source of Qt5 from git. Installed all dependencies like Python, Perl, etc. When I ran the following command configure.bat -static -opensource -release -nomake examples -nomake tests -platform win32-g++ -c++11 -opengl desktop -no-icu -skip qtwebkit Everything was fine and the config program said "Qt is now configured for building. Just run mingw32-make." When I execute as requested, it ran for

问题 I have a QDialog subclass that contains a spacer as its only immediate child; all of the window’s UI elements are contained in the spacer. The user cannot change the window size directly, but UI elements will be shown or hidden as the user interacts with the window. I’d like the dialog to resize each time this happens so that the spacer (and the dialog itself) always takes up the minimum possible amount of space. How can I configure my dialog and my spacer to get the desired behavior? (This

问题 Following my previous post I am implementing a command log using QTextEdit . The way it works is that every time the user interacts with the user interface the action is recorded inside a QTextEdit Command Log shown below. I successfully associate an image to every action (e.g. pushing a button, checking a box etc) but as you see in the print screen below the image is not resizing and everytime the user does something, instead of having an additional line, the image is put next to the other:

问题 I am writing a small application using Qt and QML that uses the example in the Qt documentation WebEngine Quick Nano Browser. In this example I am trying to access to my email.

问题 In http://qt-project.org/doc/qt-5/qabstractspinbox.html#specialValueText-prop there is an example of how to restrict a QSpinBox. It says: zoomSpinBox->setSingleStep(10); My problem is that I would like to have a QDateTimeEdit where the user can only specify date times by quarter hours aka 15 minutes. Like 2014-12-12 12:30:00 is valid and possible but 2014-12-12 12:10:00 is not. Is there any easy way to accomplish this, as I couldn't find a way. One rather complicated solution would be to

问题 I'm developing a little application with Qt5 and QML (QtCreator and C++). I would like to display a map with countries and when user passes the mouse over a country I would like to change the color of the country, thought it would be easy, and it is if all countries were rectangles. Image { id: mycountry width: 250 height: 250 source: "images/myCountry_gray.png" MouseArea { anchors.fill: parent hoverEnabled : true onEntered: { region.source = "images/myCountry_red.png" } onExited: { region

问题 I can't seem to find the glGenBuffer function in Qt5, my include list looks like #include <QtOpenGL/qgl.h> #include <QtOpenGL/qglbuffer.h> #include <QtOpenGL/qglcolormap.h> #include <QtOpenGL/qglframebufferobject.h> #include <QtOpenGL/qglfunctions.h> #include <QtOpenGL/qglpixelbuffer.h> #include <QtOpenGL/qglshaderprogram.h> #include <GL/GLU.h> I am trying to do something like the following example: http://qt-project.org/doc/qt-5.0/qtopengl/cube.html Where is it? 回答1: I know I'm late, but

问题 with functions QApplication::desktop()->screenCount(); QApplication::desktop()->screenGeometry(); I find how much screens exist on my system and on which screen coordinates they are located. Now I want to find out on which screen a QWidget is located at. How can I do that? Do I have to check the coordinates of the QWidget against the screen-coordinates or is there a more elegant way for this which returns the screen-number directly? Thanks! 回答1: I think the function you should be looking for
