qt-creator

问题 I recently decided to upgrade from Qt 4.X to 5, though now it has only vs2010 supported. Whenever I start Qt Creator I get that there isn't any compiler (and there are no options in the settings to set one). Question: How do I download the vs2010 compiler? Do I have to download vs2010 itself? Will I get a debugger as well? I have tried this suggestion, but Qt didn't pick up the compiler: Using Visual Studio as a Compiler for QT Creator Sorry if this question have been asked before, but I have

问题 I would like to build a 64 bit app with Qt Creator on Windows so unfortunately I have to use MSVC compiler. I had installed Qt Creator with required SDK but still I couldn't build with MSVC2013 toolchain since I didn't have the compiler. Event though I had MSVC 2015 installed with Visual Studio 2015, that wasn't enough for Qt Creator. I didn't feel like installing Visual Studio 2013, so I copied only the MSVC 2013 compiler from my friends Visual Studio 2013 directory. Still it wasn't listed

问题 I have a Qt application with a system tray icon and a menu that shows up when right-clicking the icon. For some reason, the menu items work fine in debug mode but not in release mode. QAction* closeAction = new QAction("Close", this); QMenu* trayIconMenu = new QMenu(this); trayIconMenu->addAction(closeAction); QSystemTrayIcon* trayIcon = new QSystemTrayIcon(this); trayIcon->setContextMenu(trayIconMenu); QIcon trayIconIcon("Application.png"); trayIcon->setIcon(trayIconIcon); trayIcon->show();

问题 I am using Qt Creator( without using any of Qt libraries) to test a Hello World project of FLTK2.0. But I am getting errors like: Errors: UpBox.cxx:-1: error: undefined reference to SelectObject@8' UpBox.cxx:-1: error: undefined reference to SetROP2@8' UpBox.cxx:-1: error: undefined reference to PatBlt@24' UpBox.cxx:-1: error: undefined reference to CreatePatternBrush@4' UpBox.cxx:-1: error: undefined reference to DeleteObject@4' :-1: error: C:\Users\mypc\Desktop\FLTK\fltk-2.0-win-bin\lib

问题 I have simple console application in C++ written in Qt Creator 2.4.1 on Kubuntu 12.04. My app have simple menu where you choose what you want to do (using std::cin and getline() ). The problem is that I cannot input data in console in Qt Creator. So I use option "Run in terminal" (xterm). But when I want to run debugger I get "ptrace operation not allowed". So: In QtCreator console I cannot input data (debugger working) In terminal I cannot use debugger (ptrace operation not allowed) I need

问题 I know that there is tons of topic similar like this, I try to implement answer from them and I still have no results. I take some sample project from qt creator to play with this. I play with changing visibility of qml files ( treat every file as other screen). After lunching 3rd screen I want to make the second one invisible. Here Is the code where I want change property in it: MyLuncherList.qml import QtQuick 2.0 Rectangle { Item { id:ei visible:false clip: true property url itemUrl

问题 Sometimes (not always), certain text items in the Qt Creator UI are broken: Any idea what causes it? Or a workaround? Maybe the problem is my cheap video card (an Intel on-board one). This theory is supported by the fact that Creator is probably QML-powered by now, meaning it's running on OpenGL. I tried restarting Creator and that fixed it, but after switching between the Welcome and Edit tabs a few times, it happens again. I tried making Creator's UI use the software QML renderer, rather

问题 I've recently set up qt creator to work with SFML, and I tried running a piece of code as a test to see if it works. I must note the code bellow works perfectly in Codeblocks IDE but in qt creator it simply displays a console with the text "Press RETURN to close this window..." #include <SFML/System.hpp> #include <SFML/Window.hpp> #include <iostream> using namespace std; using namespace sf; Window w(VideoMode(350,350,32), "Tic Tac Toe"); Event e1; const Input& in1 = w.GetInput(); int main() {
