setting text also changes color?

[drhex]

Here is a small prog that just sets a color and some text in a QTextEdit.
(QT 4.2 on X11)

#include <QApplication>
#include <QTextEdit>
 
int main( int argc, char **argv )
{
    QApplication app( argc, argv );
 
    QTextEdit t;
    qDebug("init color: %08x", t.textColor().rgb());
 
    t.setTextColor(0xdd9933);
    qDebug("after set color: %08x", t.textColor().rgb());
 
    t.setPlainText("Some text");
    qDebug("after set text: %08x", t.textColor().rgb());
 
    t.show();
    app.exec();
    return 0;
}

#include <QApplication>
#include <QTextEdit>

int main( int argc, char **argv )
{
    QApplication app( argc, argv );

    QTextEdit t;
    qDebug("init color: %08x", t.textColor().rgb());

    t.setTextColor(0xdd9933);
    qDebug("after set color: %08x", t.textColor().rgb());

    t.setPlainText("Some text");
    qDebug("after set text: %08x", t.textColor().rgb());

    t.show();
    app.exec();
    return 0;
}

To copy to clipboard, switch view to plain text mode 

The console output is:

init color: ff000000
after set color: ffdd9933
after set text: ff000000

init color: ff000000
after set color: ffdd9933
after set text: ff000000

To copy to clipboard, switch view to plain text mode 

Apparently, setting the text has the side-effect of resetting the current color. Looks like a bug to me. Anyone who can interpret it as a "feature"?

This is probably happening because you are using setPlainText().

Try using

textCursor()->insertText();

[drhex]

textCursor()->insertText() works. (or I could have set the color again after setting the text)
but why does setPlainText() change the color?

[munna]

From the docs

Changes the text of the text edit to the string text. Any previous text is removed.
text is interpreted as plain text.

Plain text means black as text color and probably "Arial" as font. This might even be OS specific.

The text set with setPlainText() was rendered in the color set just previously with setTextColor(), not black. I'll ask the Trolls.

The Trolls says it will be fixed in QT 4.3
