connect() returns true but slot not called

[OriginalCopy]

connect() on the line 19 returns true, all the widgets are set up properly, so the line 20 works, yet the slot is never called. Why ? Where did I do a mistake ?

#include "irc_settings.h"
#include "MainWindow.h"
#include <QtGui>
#include <QtDesigner>
 
IRC_Settings::IRC_Settings( QWidget *parent) : QWidget(parent) {
	dbg() << "setting up irc settings form";
	QFormBuilder builder;
	QFile file(":/forms/irc_settings.ui");
	file.open(QFile::ReadOnly);
	QWidget *myWidget = builder.load(&file, this);
	file.close();
 
	lineEdit_new_nickname = qFindChild<QLineEdit*>(this,"lineEdit_new_nickname");
	lineEdit_new_nickname->setText("foo");
	listWidget_nicknames = qFindChild<QListWidget*>(this,"listWidget_nicknames");
	toolButton_add_nickname = qFindChild<QToolButton*>(this,"toolButton_add_nickname");
 
	dbg() << "connecting toolButton_add_nickname to listWidget_nicknames" << connect(toolButton_add_nickname,SIGNAL(triggered(QAction*)),this,SLOT(slot_add_new_nickname(QAction*)));
	listWidget_nicknames->addItem(lineEdit_new_nickname->text());
	QVBoxLayout *layout = new QVBoxLayout;
	layout->addWidget(myWidget);
	setLayout(layout);
}
void IRC_Settings::slot_add_new_nickname(QAction* action) {
	dbg() << "adding new nickname:" << lineEdit_new_nickname->text();
	listWidget_nicknames->addItem(lineEdit_new_nickname->text());
}
 
IRC_Settings::~IRC_Settings() {
 
}

Did you trigger the toolButton_add_nickname button after making the connection?

[OriginalCopy]

sure, I do it after I see "connecting toolButton_add_nickname to listWidget_nicknames true" on the stderr

[wysota]

By clicking on it? Could you connect the clicked() signal as well and see if it works?

[OriginalCopy]

that works. I'll use that and I'm going to submit a bug report to trolltech (again). Thank you

[wysota]

Bug report about what? The fact that a signal is not emitted doesn't mean it's a bug. If you didn't associate any action object with the button, I don't see a reason why you connect to the signal and expect it to be emitted. The docs state the signal is related to associated actions (if you use addAction() and/or setDefaultAction() on the button, the signal will probably get emitted).

Wysota is right. This is not a bug. If you don't have any QActions added to your tool button you won't get the triggered signal.

Triggered is when you have multiple actions for one buttons, like this:

colorButton = new QToolButton(this);
colorButton->setPopupMode(QToolButton::InstantPopup);
colorButton->addAction(textColorAct);
colorButton->addAction(itemColorAct);
colorButton->setDefaultAction(textColorAct);
connect(colorButton, SIGNAL(triggered(QAction*)), this, SLOT(onColorActionTriggered(QAction*)));

colorButton = new QToolButton(this);
colorButton->setPopupMode(QToolButton::InstantPopup);
colorButton->addAction(textColorAct);
colorButton->addAction(itemColorAct);
colorButton->setDefaultAction(textColorAct);
connect(colorButton, SIGNAL(triggered(QAction*)), this, SLOT(onColorActionTriggered(QAction*)));
