Hardcoded fonts in Qt designer

**mpi** · 26th January 2012, 17:57

On Ubuntu 11.04:

Start Designer and use the basic widget template
Add a QLabel.
Right-click the label and enter rich-text editing
Add some text with a superscript.

Now click the source tab. This is what I find:

Qt Code:

Switch view

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">
<html><head><meta name="qrichtext" content="1" /><style type="text/css">
p, li { white-space: pre-wrap; }
</style></head><body style=" font-family:'Ubuntu'; font-size:11pt; font-weight:400; font-style:normal;">
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">A<span style=" vertical-align:super;">2</span></p></body></html>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">
<html><head><meta name="qrichtext" content="1" /><style type="text/css">
p, li { white-space: pre-wrap; }
</style></head><body style=" font-family:'Ubuntu'; font-size:11pt; font-weight:400; font-style:normal;">
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">A<span style=" vertical-align:super;">2</span></p></body></html>

To copy to clipboard, switch view to plain text mode

Now, do perform the same exercise on Windows 7. Then the rich-text source will look like this:

Qt Code:

Switch view

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">
<html><head><meta name="qrichtext" content="1" /><style type="text/css">
p, li { white-space: pre-wrap; }
</style></head><body style="
font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400;
font-style:normal;">
<p style=" margin-top:0px; margin-bottom:0px;
margin-left:0px; margin-right:0px; -qt-block-indent:0;
text-indent:0px;"><span style="
font-size:8pt;">A</span><span style=" font-size:8pt;
vertical-align:sub;">1</span></p></body></html>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">
<html><head><meta name="qrichtext" content="1" /><style type="text/css">
p, li { white-space: pre-wrap; }
</style></head><body style="
font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400;
font-style:normal;">
<p style=" margin-top:0px; margin-bottom:0px;
margin-left:0px; margin-right:0px; -qt-block-indent:0;
text-indent:0px;"><span style="
font-size:8pt;">A</span><span style=" font-size:8pt;
vertical-align:sub;">1</span></p></body></html>

To copy to clipboard, switch view to plain text mode

So the fonts in the rich text is hard coded. Now, if you work in a cross-platform development where developers (on different OS's ie.) share UI files via a GIT repository, this quickly becomes a mess.

Any suggestions?

Maybe preprocess all .ui files and chop out the line:

Qt Code:

Switch view

<body style="font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400; font-style:normal;">

<body style="font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400; font-style:normal;">

To copy to clipboard, switch view to plain text mode

Just use source tab ONLY! Trash the heade leave only body intact.
It will work. No problems with merging when using source tab only (remove also body and page tag).

Problem comes from QTextDocument and that QTextDocument::setHtml accept simple html but after that QTextDocument::toHtml returns an extra header.

Edit: In fact it works only if you set text value using property inspector and dont touch that text difrent way (that sucks), so don't click the label.
