absfrm

Hi
I want to generate code for Clicked on QLabel event such as QpushButton
but QLable just has these events :
@
LinkActivated();
linkHovered();
destroyed();
customContextMenuRequested();
@
can i do it?

You can use "eventFilter":http://doc.qt.nokia.com/latest/qobject.html#eventFilter for this.

Are you trying to make the label work like a button ? In that case ,one easy way is to use QPushButton::setFlat(true) to set the 'flat' property and the button will look like a label.
Or are you completely customizing the QLabel ?

You can create a class that inherits from QLabel which will implement the following protected function:
@
signals:
void clicked();
protected:
void mousePressEvent ( QMouseEvent * evt);
void mouseReleaseEvent ( QMouseEvent * evt);
@

You could set it to emit a clicked signal every time mouseReleaseEvent function is called.

You shoud ceate a SLOT to receive the signal from your QLabel. Try this:
@
connect(your_label, SIGNAL(clicked()), this, SLOT(onClicked()));

There is no clicked signal in QLabel.

I don't see the point in using a clickable label; use either a button or a link (with an appropriate style).

I agree with fluca1978: why do you want to confuse the user by making something that doesn't hint at being clickable an active component?

fguimaraes

Sorry, my mistake. But, as fluca said you can use a pushbutton and change the appearance through QSS.

bq.as fluca said you can use a pushbutton and change the appearance through QSS.

QPushButton::setFlat(true) will also do :) (which i have already told^)

"Here":http://developer.qt.nokia.com/wiki/How_do_Qlabel_be_clickable you can find the source for 'click'able QLabel

//Off Topic : edit link of previous post is not working for me. :(
Anybody has the same problem ?

favoritas37

You have the option to make it emit the clicked signal either when mouse gets pressed or when mouse gets release (i prefer the second one). Whatever feels better to you.

Rahul Das

yea, and there is a "how to":http://developer.qt.nokia.com/wiki/How_do_Qlabel_be_clickable / wiki page to do this saying the same as favoritas37 said :)

Rahul, i hope you don't mind, i edited the wiki by removing the slot because it caused the signal to be emitted 2 times. And also i changed the name of the new class to ClickableLabel since this is how it is mentioned in the description. Is that ok?

Rahul Das

Thanks, and thats perfect. :) Two times the same signal, was a careless part anyway.
