Qt layout issue

Hey there,

I have an issue with the QVBoxLayout.

I'm dynamicaly changing widget inside the layout : removing one and inserting another.

- When the new widgets occupies more space : the layout stretches and everything works fine.

But,

- When the new widgets occupies less space than the previous one : the layout doesn't shrink and keep its dimension.

Any way to force the resize of the layout ?

Try calling invalidate after adding the widget,

Regards

Thanks,

Here is my code for my "settable widget" :

Code:

---

//=============================================================================
//=============================================================================
 
void ZeSettableWidget::setWidget(QWidget & widget)
{
	ClearWidget();
 
	mWidget = &widget;
 
	mLayout.addWidget(mWidget);
	mWidget->show();
 
	mLayout.invalidate();
}

Doesn't seem to work, the layout doesn't shrink back to the smaller widget size.

Yes, you are right, it will never work like this.
You have to recreate the layout each time.

I think there are a few similar threads/

Regards

I'm not sure to know what I'm searching for.

Code:

---

layout->setSizeConstraint(QLayout::SetFixedSize);

---

Code:

---

mLayout.setSizeConstraint(QLayout::SetFixedSize);

---

worked with me.

Thanks.
