Qt layout memory issue

[bunjee]

Hello,

I have an issue with Qt layout.

That piece of code is working :

ZeTextWidget * textWidget = new ZeTextWidget ("Salut"); // Creating a new Widget
ZeTopListWidget * topListWidget1 = new ZeTopListWidget(*textWidget); // Adding the widget to the layout
topListWidget1->Clear(); // Clearing the object / layout
delete topListWidget1; // Deleting the object containing the layout

ZeTextWidget * textWidget = new ZeTextWidget ("Salut"); // Creating a new Widget
ZeTopListWidget * topListWidget1 = new ZeTopListWidget(*textWidget); // Adding the widget to the layout
topListWidget1->Clear(); // Clearing the object / layout
delete topListWidget1; // Deleting the object containing the layout

To copy to clipboard, switch view to plain text mode 

That one isn't :

ZeTextWidget textWidget("Salut"); // Creating a local variable
ZeTopListWidget * topListWidget1 = new ZeTopListWidget(textWidget);  // Adding the widget to the layout
topListWidget1->Clear(); // Clearing the object / layout
delete topListWidget1; // Deleting the object containing the layout

ZeTextWidget textWidget("Salut"); // Creating a local variable
ZeTopListWidget * topListWidget1 = new ZeTopListWidget(textWidget);  // Adding the widget to the layout
topListWidget1->Clear(); // Clearing the object / layout
delete topListWidget1; // Deleting the object containing the layout

To copy to clipboard, switch view to plain text mode 

When creating my "ZeTopListWidget " I'm doing this :

mLayout.addWidget(&widget);
mWidget = &widget;

mLayout.addWidget(&widget);
mWidget = &widget;

To copy to clipboard, switch view to plain text mode 

When clearing my "ZeTopListWidget" I'm doing this :

if (mWidget)
{
	mLayout.removeWidget(mWidget);
	mWidget = NULL;
}

if (mWidget)
{
	mLayout.removeWidget(mWidget);
	mWidget = NULL;
}

To copy to clipboard, switch view to plain text mode 

When I'm:
- Adding an allocated variable to the layout.
- Clearing the layout (removeWidget).
- Deleting the object containing the layout.
-> It Works.

BUT if I'm:

- Adding a local variable to the layout.
- Clearing the layout (removeWidget).
- Deleting the object containing the layout.
-> Crash on the delete line.

Obviously something is going wrong when the Layout default dtor is called.
Provided the fact that I remove the assigned widget before deleting my object and thus its member's layout: it should work fine.

Is there something I'm missing ?
