QGridLayout update

[sophister]

Hi to all:

I use a QGridLayoutin my QMainWindow, and have added some QToolButtonsinto it. But when I delete some QToolButtons in another dialog, the QGridLayout don't update itself. What's worse, even if I call the QGridLayout::update(),it still show part of the QToolButtonsthat have been deleted!!
why??

Without seeing any code, i would suspect that you only think that you have deleted these buttons. Are you really sure that they have been deleted?

Yeah, I'm sure I have deleted the chosen QToolButton, using the following codes:

ui->gridLayout->removeWidget(iter.value());

ui->gridLayout->removeWidget(iter.value());

To copy to clipboard, switch view to plain text mode 

the

iter.value()

iter.value()

To copy to clipboard, switch view to plain text mode 

returns the a pointer to the QToolButtonin the GRridLayoutto be deleted.

What's the "iter.value()" parent? What's happen if you additionaly call

delete iter.value();

delete iter.value();

To copy to clipboard, switch view to plain text mode

Actually, I keep some QToolButtons in an QMap<QString, QToolButton *>,and I through the Iterator to delete the chosen QToolButton, and delete it in the QGridLayoutat the same time.
But, failed
