automatic Size policy when resizing window

SimonChoops

hello,
I'm searching from this morning how to do that ... I tried lot of things but never works.
I would like to automaticaly resize policy when resizing window
other thing, I tried to but the background in black ... but tried some tuto without success...
If somebody can help me please:

QWidget *widgetFondNoir = new QWidget();

// widgetFondNoir->setStyleSheet("background-color: black");
auto palette = widgetFondNoir->palette();
palette.setColor(QPalette::Window, Qt::blue);
widgetFondNoir->setPalette(palette);

//Variables
test=0;
qTimeHeure.setHMS(0,0,00,000);
qTimeHeureMeeting.setHMS(0,0,00,000);
qTimeHeureRestante.setHMS(0,45,00,000);

QLabel *labelHeure = new QLabel(this);
QLabel *labelHeureRestant1 = new QLabel(this);
QLabel *labelHeureRestant2 = new QLabel(this);
QLabel *labelHeureRestant3 = new QLabel(this);

labelHeure->setText(" HEURE : 19:25:54 ");
labelHeure->setAlignment(Qt::AlignCenter);
//labelHeure->setFont(QFont("Comic Sans MS", 14));

labelHeureRestant1->setText(" TRACK WALK : 19:25:54 ");
labelHeureRestant1->setAlignment(Qt::AlignCenter);
//labelHeureRestant1->setFont(QFont("Comic Sans MS", 14));

labelHeureRestant2->setText(" Mechanical_Fire_Up : 19:25:54 ");
labelHeureRestant2->setAlignment(Qt::AlignCenter);
//labelHeureRestant2->setFont(QFont("Comic Sans MS", 14));

labelHeureRestant3->setText(" Test_Session_4 : 19:25:54 ");
labelHeureRestant3->setAlignment(Qt::AlignCenter);
//labelHeureRestant3->setFont(QFont("Comic Sans MS", 14));

//Layout
QGridLayout *layoutPrincipal = new QGridLayout(widgetFondNoir);
QGridLayout *layoutMilieu = new QGridLayout(widgetFondNoir);

layoutPrincipal->addWidget(boutonQuitter,12,10,1,3);
layoutPrincipal->addWidget(boutonConnect,12,2,1,3);
layoutMilieu->addWidget(labelHeure,1,3,2,4);
layoutMilieu->addWidget(labelHeureRestant1,3,2,2,7);
layoutMilieu->addWidget(labelHeureRestant2,6,2,2,7);
layoutMilieu->addWidget(labelHeureRestant3,9,2,2,7);
layoutPrincipal->addLayout(layoutMilieu,0,6);
this->setLayout(layoutPrincipal);

Why do you create two layouts for the same widget?

Hello,

This is to have a layout inside another one, because with just one when I resize it makes strange things.
maybe it is not the go way to do but for the moment doesn't matter ^^ I would like the policy resized in the same time the window is resized...
you now how to ?

Thank you

Hi,

Passing a parent to a layout will apply that layout on the parent so if you want to have a layout in another layout, don't give a partent to that second layout and use the addLayout method of the main one.

Hello,

Ok I will do that but an idea for the main subject ? resize text in function of window's size ?

Where did you ask this question?
You ant to automatically resize the text when the widget gets resized? You have to implement this by your own by e.g. overriding QWidget::resizeEvent()

Hello,
on my first message :) and this is the name of the topic as well.

I have to implement it really ? it's strange that is not possible basically.

I don't have the level in QT to do this...

anyway
Thank you for your answer

You seemed to ask several different questions, it's not clear (to me, maybe others) just what it is you want.

What resizing did you want/expect? When did "resize text" come into what you were asking? Resize in what way? I see you have lines commented out which had setFont() and a text size number, is that what you want/expect to change? So the font changes size when other things resize??
