How to set size and font for a QPushbutton

mostefa

Hi,

@tomy you can customize your QPushButton style with qt stylesheet, take a look at:

http://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qpushbutton

For your need :

QPushButton#my_button
{
font: bold;/or italic/
background-color: red;
font-size: 36px;/for example/
height: 48px;/for example/
width: 120px;/for example/
}

You can change the position of the button with the layout of the parent widget

Thank you. I looked at this link but couldn't find useful method for the tasks I mentioned.

Would you please, given the button my_button do the changes?

mostefa

my_button->setStyleSheet("font: bold;background-color: red;font-size: 36px;height: 48px;width: 120px;}

Three errors:

1-missing terminating " character
my_button ->setStylesheet("font: bold;background-color: red;font-size: 36px;height: 48px;width: 120px;}

2- 'class QPushButton' has no member named 'setStylesheet'
my_button ->setStylesheet("font: bold;background-color: red;font-size: 36px;height: 48px;width: 120px;}

3- expected ')' before ';' token
connect(signalMapper, SIGNAL(mapped(QString)), this, SLOT(get(QString)));

Sorry , the function is setStyleSheet and not setStylesheet

try with this line:

my_button->setStyleSheet("font: bold;background-color: red;font-size: 36px;height: 48px;width: 120px;");

Thank you. It worked now. Using it we have:
font
background-color
font-size
height & width
These are good and applicable. But what for:
Positioning and the color of font?
Do we have such facilities?

@tomy

Glad to see that this helped you,

for font color , the property is color, you can write : color: white;//for example,

I advise you to list of available properties that you can use with stylesheet from Qt doc:

http://doc.qt.io/qt-5/stylesheet-reference.html#list-of-properties

and to see stylesheet example from qt examples:

http://doc.qt.io/qt-5/qtwidgets-widgets-stylesheet-example.html

Thank you. Color was used but about positioning a button not yet!
I fount this using your link.
It appears to be what I need. But how to use it? I tried some ways using the contents of the page but no result.

and to see stylesheet example from qt examples:

http://doc.qt.io/qt-5/qtwidgets-widgets-stylesheet-example.html

I also looked at it. It's about Designer, which widgets can be customized in property window (coding seems useless)

@tomy

Usually for positioning : buttons,widgets ,i am using Layout , i never used position property of stylesheet not with stylesheet,i do you have a layout on your application? are you using Qt designer ?

If you are using Qt Designer positions of buttons can be changed directly with drag and drop

And yes widgets can be customized from qt Designer , on your mainWindow , on stylesheet property.

@mostefa
The problem is that I don't use Designer, just pure code.
I have a gridlayout, QVBoxlayout and QHBoxlayout for laying out the widgets.

mostefa

@tomy

You can position your widget width QGridLayout, without any problem

http://doc.qt.io/qt-5/qgridlayout.html#addWidget

When you add widgets with gridLayout you choose the row , the column , the row span and column span, and the alignement

row and column are represented on the following picture:
