setText and html

[mattia]

Hello, if i have a QLabel i can do this:

ui.label->setText ( tr ( "<b><font color=red>Label</font></b>" ) );

and i see "Label" in red bold

instead of, if i have a QCheckBox i can't do this:

ui.checkBox->setText ( tr ( "<b><font color=red>Check box</font></b>" ) );

or better, i get no errors but it shows on the GUI

<b><font color=red>Check box</font></b>

and not "Check box" in red bold.
Any Ideas?

Checkboxes don't understand rich text. Set the font using QCheckBox::setFont() or use a style sheet.

this way is good for me:


QFont font(QFont::Bold);
ui.checkBox->setFont (font);
ui.checkBox->setText ( tr ( "text" ) );

but what shuld i do to set the red color?

thx

Use QPalette:

QPalette p( ui.checkBox->palette() );
...
ui.checkBox->setPalette( p );

i have to get the palette and change the color?
im not to skilled with this stuff...can you show me how to do it?
thx

I gave you 66% of the necessary code. See QPalette::ColorGroup.

I tried in this way


QPalette p( checkbox->palette() );

QColor c(Qt::red);
p.setColor(QPalette::Text,c);

checkbox->setPalette(p);

but nothing...why doesn't it work?
thx

You should change the QPalette::WindowText colour.

Hi, with this code i correctly set bold-red text on checkbox but i have some problem to show it using gnome, i just get a bold-black text.
Any hint?


void setRichTextOnCheckBox ( QCheckBox * checkbox , QString message )
{
QFont font ("" , 9 , QFont::Bold );
checkbox->setFont( font );


QPalette p ( checkbox->palette() );
QColor c(Qt::red);
p.setColor(QPalette::WindowText,c);
checkbox->setPalette(p);

checkbox->setText( message );
}

Can you see the red text if you start your application with -style plastique switch? Do you use any stylesheets?

[mattia]

what the argument

-style plastique

should do?
thx

[jacek]

If will change the default style to Plastique.
