Get object, which have received signal
-
Hello. How to get object, which have received signal? Look at that code:
@ for (var idx=0;idx<leftButtonSettings.length;idx++) {
left_objects[idx] = component.createObject(left_menu_flick.contentItem, {
"x": 0,
"y": 0
});
left_objects[idx].x = (left_menu_flick.width-left_objects[idx].width)/2;
if (idx==0) {
left_objects[idx].y = y_offset
} else {
left_objects[idx].y = left_objects[idx-1].y + left_objects[idx].height + y_offset
}
left_objects[idx].name_text = leftButtonSettings[idx][0]
left_objects[idx].desc_text = leftButtonSettings[idx][1]
left_objects[idx].url = leftButtonSettings[idx][2]
left_objects[idx].clicked.connect (function() {
CMainWindow.tryLoadFromNetwork(object.desc_text) //What I must write here?
showLoadingStatic();
})
}@
in line "CMainWindow.tryLoadFromNetwork(object.desc_text)" I want to send text from field url to function CMainWindow.tryLoadFromNetwork which have written in C++. But how to get object in that case to get url field? Thanks -
Just use "QObject::sender()":http://qt-project.org/doc/qt-4.8/qobject.html#sender, if the code you posted above is inside a slot that received a signal and the object you're looking for is the sender of the signal.
Then you could do something like this:
@
if(qobject_cast<QWidget*>(QObject::sender())) // cast to the appropriate class here, QWidget is just as an example
{
CMainWindow.tryLoadFromNetwork(qobject_cast<QWidget*>(QObject::sender()).desc_text) // cast to the appropriate class here, QWidget is just as an example
}
