[Qt-interest] basic question about button and slot

[ri at eeda.denso.co.jp]

Thank you
 
then what about I have another button in the dialog and want to access memberA?
 
I still ain't sure that if I write the anotherButtonClicked() slot in the myDialog.cpp
 
how do I get all parent's members in the slot .

Hi,
As the button is in QWidget (myWidget.cpp), I think that you need to connect the clicked() signal to your slot buttonClicked() in the myWidget.cpp itself and the slot should also be the part of the same.

	hey there
	 
	here's where I am:
	 
	+ a window (QWidget) (myWindow.cpp) with a button
	+ a click on the button will create a dialog ( myDialog.cpp ) which takes the window as its parent 
	+ the dialog wants to read some members of the parent
	 
	Now, where should I write the buttonClicked() slot?
	 
	in the myWindow.cpp or the myDialog.cpp?
	 
	I tried to put it in myDialog.cpp( which I think is natrual )
	 
	there I wrote:
	 
	void myDialog::buttonClicked()
	{
	   ... ...
	 
	   this->parentWidget()->memberA->xxx();
	 
	   ... ...
	 
	}
	 
	But got a  "class QWidget' has no member named 'memberA' " error.
	 
	Is it necessary to implement the buttonClicked() slot in myWindow.cpp?
	or am I just doing things in a wrong way?
	 
	I know it sounds like an entry-level question but I do need some help.
	thanks in advance!
