QTextEdit Help !

[chendy]

Hello,
I use a QTextEdit to display some texts, setting it to ReadOnly, but I want the texts cannot be selected, just like QLabel. As well, there should be scrollbar when the dlg is too small.

I am a beginner in qt4, PLZ help me.
thanks~~~

Have a look at the TextInteractionFlags of QTextEdit: http://doc.trolltech.com/4.5/qtextedit.html#textInteractionFlags-prop

A vertical scrollbar is added automatically when the text is higher than the height of the QTextEdit.
If you want a horizontal scrollbar you have to configure the LineWrapMode: http://doc.trolltech.com/4.5/qtextedit.html#lineWrapMode-prop

and you can customize ScrollBarPolicy like this:


QTextEdit * te = new QTextEdit;
te->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOn);

and that code gives you always visible scrollbar.

Another thing is that you can put QLabel in QScrollArea if you want to have just a QLabel functionality (look at screenshot - left is QTextEdit, right is QScrollArea with QLabel inside)
