[SOLVED] What should i do to resize the dialog the proper way?

Leon

So i have this dialog,

the arrow thing is a checkbox and when you click it:

when you click it back (uncheck)

And this is ugly not resizing the dialog back like image 1. Am i right? So i have no idea how to do it because ->resize won't work in this case.
My code creating the dialog

@ createOptionsGroupBox();
createButtonsLayout();
mainLayout = new QVBoxLayout;
mainLayout->addWidget(optionsGroupBox);
mainLayout->addLayout(buttonsLayout);
setLayout(mainLayout);

void custom_command::createOptionsGroupBox()
{
optionsGroupBox = new QGroupBox();
optionsGroupBoxLayout = new QGridLayout;
optionsGroupBoxLayout->addWidget(ui->label, 0, 0, 2, 2);
optionsGroupBoxLayout->addWidget(ui->label_2, 2, 0);
optionsGroupBoxLayout->addWidget(ui->de, 2, 1);
optionsGroupBoxLayout->addWidget(ui->checkBox, 3,0);
optionsGroupBoxLayout->addWidget(ui->label_4, 4, 0);
optionsGroupBoxLayout->addWidget(ui->command, 5, 0);
optionsGroupBoxLayout->addWidget(ui->label_5, 6, 0);
optionsGroupBoxLayout->addWidget(ui->label_6, 7, 0);
optionsGroupBoxLayout->addWidget(ui->add_argument, 8, 1);
optionsGroupBoxLayout->addWidget(ui->rmButton, 9, 1);
optionsGroupBoxLayout->addWidget(ui->clear, 10, 1);
optionsGroupBoxLayout->addWidget(ui->listWidget, 8, 0, 3, 1);
optionsGroupBox->setLayout(optionsGroupBoxLayout);
}

void custom_command::createButtonsLayout()
{
buttonsLayout = new QHBoxLayout;
buttonsLayout->addWidget(ui->help);
buttonsLayout->addStretch();
buttonsLayout->addWidget(ui->cancel);
buttonsLayout->addWidget(ui->test);
buttonsLayout->addWidget(ui->apply);
}@

And i use ->hide and ->show to work with the checkbox

You could use QPropertyAnimation and animate resizion of the whole dialog. You could save the geometry before it expands into the animation.

Yeah but i can't resize it.. I have noooo idead why i can't resize it:

@if(!this->isMaximized())
this->resize(QSize(this->width(),this->height()-200));@

The reason must be something about the groubox.. Anyone can give me a hint?

adam.bogocz

so you cannot resize it from CPP and also by mouse?

You should take a look at shape-changing dialogs in C++ GUI Programming with Qt4 Second Edition. ;)

I had a similar problem that I solved by inserting a vertical spacer item in between (in your case) the "Show Details" button and the details you're showing. In other words

//-------------------informative text here -------------------//
//
//

Show Details
//----------------------vertical spacer----------------------//
// Command...etc etc etc
// Help and other buttons

I then connected the "Show Details" button clicked() signal to a slot that simply hides or shows the widget containing the information that should be visible/not visible.

Something like:

@
void Widget::toggleVisibility()
{
if( customComand->isVisible() )
{
customComand->hide();
showDetailsButton->setArrowType( Qt::DownArrow );
} else {
customComand->show();
showDetailsButton->setArrowType( Qt::RightArrow );
}
}
@

I hope this makes sense.

Take a look at the Extension Example in Qt Assistant. The resizing magic is:

@
mainLayout->setSizeConstraint(QLayout::SetFixedSize);

well i read "shape-changing dialogs in C++ GUI Programming with Qt4 Second Edition"
and it solved my problem :)

i just had to make a second groubox which consisted the widgets that i wanted to hide/show..
Thank you for your answers! :)

Maybe I should take a look at "Shape-changing dialogs in C++ GUI Programming with Qt4 Second Edition" also! :)
