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/qtexted...tionFlags-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/qtexted...eWrapMode-prop

and you can customize ScrollBarPolicy like this:

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

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

To copy to clipboard, switch view to plain text mode 

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)
