QAction无法连接到我的插槽 [英] QAction won't connect to my slot
问题描述
我试图用Qt制作IHM,然后从制作基本菜单(文件,编辑...)开始. 到目前为止,我的菜单包含文件",然后显示新建项目,打开项目,退出". 看起来不错,但我的问题是我似乎无法触发这些操作(单击它们或通过快捷键).
I'm trying to make an IHM with Qt, and I started by making a basic menu (File,Edit...). So far, I have my menu containing "File", which then display "New Project, Open Project, Exit". Look great, but my problem is I can't seem to trigger these Action (clicking them or by key shortcut).
这是我的广告位:
void KoriganEngine::launchNewProjectWidget(){
//External QWidget
m_nwProj = new NewProjectWidget(NULL,Qt::MSWindowsFixedSizeDialogHint);
m_nwProj->show();
}
如果在连接了按钮的情况下使用此插槽,则新的QWidget将正确显示. 但是,不可能通过动作来做同样的事情...
If I use this slot with a pushbutton connected, my new QWidget is displayed properly. However, impossible to do the same thing with an action...
这是我的操作和菜单的代码:
Here is the code of my actions and menu:
void KoriganEngine::KG_createMenus(){
//init actions
KG_createMenuActions();
//add menu to the bar
m_fileMenu = menuBar()->addMenu("File");
m_fileMenu->addAction(m_newProjAction);
m_fileMenu->addAction(m_openProjAction);
m_fileMenu->addSeparator();
m_fileMenu->addAction(m_quitAction);
m_editMenu = menuBar()->addMenu("Edit");
}
void KoriganEngine::KG_createMenuActions(){
m_newProjAction = new QAction("New Project...", this);
m_newProjAction->setShortcuts(QKeySequence::New);
m_newProjAction->setStatusTip(QString("Create a new Project"));
connect(m_newProjAction, SIGNAL(trigerred()), this, SLOT(slottest()));
m_openProjAction = new QAction("Open Project...", this);
m_openProjAction->setShortcuts(QKeySequence::Open);
m_openProjAction->activate( QAction::Hover);
connect(m_openProjAction, SIGNAL(trigerred()), this, SLOT(launchNewProjectWidget())); //TODO replace the slots
m_quitAction = new QAction("Exit", this);
connect(m_quitAction, SIGNAL(trigerred()), this, SLOT(quit()));
}
以及与按钮配合使用的代码:
And the code that works with a button:
connect(m_button, SIGNAL(clicked()), this, SLOT(launchNewProjectWidget()));
所以我真的不明白为什么它不应该做出同样的反应,我已经一遍又一遍地阅读了Qt示例...我一定错过了一些东西,但是如果有人想,我会比感激不尽,因为它开始让我讨厌生活:p
So I don't really get why it should not react the same, I've read the Qt examples over and over... I must have missed something, but if anyone as an idea, I'll be more than grateful, as it's starting to make me hate life :p
谢谢大家.
PS:好的,不确定我是否能很好地处理代码块的事务,在我的辩护中,使用它真的很奇怪...:p
PS: Ok, not sure I handle great the code blocks buisness, in my defence it's really weird to use... :p
推荐答案
您在触发词:P中犯了一个错误,应该是:
You made a mistake in triggered word :P It should be:
connect(m_quitAction, SIGNAL(triggered()), this, SLOT(quit()));
------
已触发,而不是触发! :)
Triggered, not trigerred! :)
