[Qt-interest] QLabel text with colon always puts colon at the front

[Keith Nicewarner]

BTW, I'm using Qt 4.3.3.
Here's the context:  I'm creating a custom designer plugin that instantiates a very simple widget that has a label and a line edit, both inside a horizontal layout.  I used designer to create the form for the widget if that matters.  My class looks like this:

class Text_Channel: public QWidget
{
    Q_OBJECT
    Q_PROPERTY(QString channel_name READ channel_name WRITE set_channel_name DESIGNABLE true)

public:
    Text_Channel(QWidget * parent = 0);

    QString channel_name() const;
    void set_channel_name(QString const & name);
    void set_value(double value);

private:
    Ui_Form ui;
    QString _channel_name;
};

The problem is here:
void Text_Channel::set_channel_name(QString const & name)
{
    _channel_name = name;
    ui.name->setText(name + ": ");
}

I'm testing the custom widget in designer by dragging my text channel onto a form and setting the channel name property in designer.

Thanks,
Keith.

There must be some other factor involved.  I cannot reproduce this in
my code in a trivial test.  I was able to call setText("FOO:") on one
of my QLabel widgets in my dialog's constructor immediately after the
setupUi(this) call, and it worked as expected.

Is there anything about the context where you make the call that might
be relevant?  Are there translations built in?  Is this called in a
slot after the dialog has been opened?
