Qt layout memory issue

[bunjee]

Thanks marcel,

Actually mWidget is a pointer on the widget.
Assigning it to NULL doesn't change a thing.

another example :

This works :

ZeTextWidget * textWidget = new ZeTextWidget("Salut");
QHBoxLayout * layout = new QHBoxLayout();
layout->addWidget(textWidget);
delete layout;
delete textWidget;

ZeTextWidget * textWidget = new ZeTextWidget("Salut");
QHBoxLayout * layout = new QHBoxLayout();
layout->addWidget(textWidget);
delete layout;
delete textWidget;

To copy to clipboard, switch view to plain text mode 

This one crashes :

ZeTextWidget textWidget("Salut");
QHBoxLayout * layout = new QHBoxLayout();
layout->addWidget(&textWidget);
delete layout;

ZeTextWidget textWidget("Salut");
QHBoxLayout * layout = new QHBoxLayout();
layout->addWidget(&textWidget);
delete layout;

To copy to clipboard, switch view to plain text mode 

Thos two pieces of code are all the same for me.

- In one case :
- I'm declaring a self allowed variable in local
- Assigning it to the layout.
- Deleting the layout
- the self allowed variable is/should be deleted at the end of the function locally.

- In another case :
- I'm declaring a pointer variable
- Allocating it myself.
- Assigning it to the layout.
- Deleting the layout
- Deleting the pointer manually.

Imho the result is/should be exactly the same.
