qt-creator

问题 Did a clean install on a new Windows 7 computer with: Visual Studio 2008 SP1 Qt SDK 1.1.4 Then I created a new project in Qt Creator. I picked "Qt Gui Application" under "Qt Widget Project" and had it target desktops with Visual C++ 2008, both debug & release (basically default settings). Then I pressed Build, and got.... qtmaind.lib(qtmain_win.obj):-1: warning: LNK4099: PDB 'vc90.pdb' was not found with 'c:\QtSDK\Desktop\Qt\4.7.4\msvc2008\lib\qtmaind.lib' or at 'C:\Users\JamesJ\Desktop

问题 I'm somewhat new to C++ and to Qt 5.2.1. I'm actually learning how to use Qt. To do it as easy as possible, I'm using Qt Creator 3.0.1. I've written this little piece of code in the main.cpp file of my project : #include <QApplication> #include <QPushButton> int main(int argc, char *argv[]) { QApplication app(argc, argv); QPushButton bouton("Hello !"); bouton.show(); return app.exec(); } And the .pro file (by default) : SOURCES += \ main.cpp I tried to make it run, then I got the issue

问题 When I have a QMainWindow with a grid layout, when resizing it with the mouse, it won't go below some minimum size that's necessary for all the controls in it to show properly. In my app I sometimes programatically hide controls, but then the window remains the same size and the rest of the controls look spread out, with too much space between them. I end up resizing the dialog manually so it doesn't look ugly. Can I programatically set the dialog's vertical size to this minimum I get when

问题 I'm using Windows 8 64-bit, Qt 5.0.2 for Windows 64-bit and Visual Studio 2012. I have no trouble compiling and running my application on 64-bit OS, but apparently it doesn't work on 32-bit OS. Is there a way to compile 32-bit application with what I have, or should I install Qt for Windows 32-bit? (I download Qt from here.) If it's possible, I would like a hint at where that option is. I'm using Qt Creator. 回答1: It's not possible with 64bit library, but you can download and install the

Can anyone tell what the problem is ? Source code of MainWindow.cpp #include <QtGui> #include <QAction> #include "MainWindow.h" MainWindow::MainWindow() { //

问题 As a newbie to Qt I am writing a small project depending on another project, located in a parallel directory. In my .pro file some .obj files are includes as below (which works). However, when creating a release I'd like to use the other project's release and not its debug path. I have checked the Qt variables and found the "TARGET example". But I failed to apply it to my LIBS , especially since the build can be for both debug_and_release , and I have no idea how to write the LIBS path then.

问题 I'm having issues getting qwt 6.1.0 to work correctly with Qt-Creator 5.1.0. It works correctly when I launch the stand alone version of Qt-Designer and everything compiles and runs correctly when I use Qt-Creator. However the designer that is built into Qt-Creator does not display the qwt widgets correctly on any forms nor give me the option to add new qwt widgets. I'm using Qt Creator 5.1.0 for Windows 64-bit (VS2012 with OpenGL). I've also downloaded and compiled Qwt 6.1.0 with the

问题 I want to use Qt Creator with MS VC++ 11 but it says there is no toolchain to build Qt. I installed Qt with the full SDK installer. What to do now? 回答1: Isn't MSVC++ 11 comes with Visual Studio 11? If so then Qt hasn't supported makespec file for that version AFAIK (correct me if I am wrong). But following are the (rough) steps for running Qt Creator with MSVC 2010 nmake/cl tool-chain.. Download Qt SDK 4.8.2 compiled using msvc-2010 toolchain from this site (second page). Install MS VC++ 2010

问题 I'm trying to get started with with C and Cuda using QT creator as the IDE. Unfortunately I'm having problems from the start and not sure where its coming from(if it started gradually it'd be easier to identify). I basically already installed CUDA(and c) and had small test programs running but I wanted to use an IDE so I installed QT creator using the instructions on: http://cudaspace.wordpress.com/2011/04/07/qt-creator-cuda-linux/ but I'm getting errors when running the example: 'linker

问题 I have a CMake project, and until now, I was using Visual C++ for developing. Using CMake-gui to generate a solution for VC++, it generates more than one project in the same solution. But when the script is loaded in qt-creator, only one project is defined, with all the code and folder tree inside, so I can not compile it (or I don't know how to do it). How can I load the cmake file to load all the projects? More info: The first CMakeList.txt has some common configuration. Then, with 'add
