Auto-scrolling QTextBrowser

[MTK358]

1 - This QTextBrowser does it by default when text is appended. When text is inserted it doesn't but it requires very little work:

MyBrowser::MyBrowser( QWidget* parent ) :
    QTextBrowser( parent ),
    atBottom( false )
{
    connect( this, SIGNAL( textChanged() ), this, SLOT( scrollToBottom() ) );
    connect( this->verticalScrollBar(), SIGNAL( valueChanged( int ) ), this, SLOT( scrolledTo( int ) ) );
}
 
void    MyBrowser::scrollToBottom( void )
{
    if( this->atBottom )
    {
        this->verticalScrollBar()->setValue( this->verticalScrollBar()->maximum() );
    }
}
 
void    MyBrowser::scrolledTo( int val )
{
    this->atBottom = val == this->verticalScrollBar()->maximum();
}

MyBrowser::MyBrowser( QWidget* parent ) :
    QTextBrowser( parent ),
    atBottom( false )
{
    connect( this, SIGNAL( textChanged() ), this, SLOT( scrollToBottom() ) );
    connect( this->verticalScrollBar(), SIGNAL( valueChanged( int ) ), this, SLOT( scrolledTo( int ) ) );
}

void    MyBrowser::scrollToBottom( void )
{
    if( this->atBottom )
    {
        this->verticalScrollBar()->setValue( this->verticalScrollBar()->maximum() );
    }
}

void    MyBrowser::scrolledTo( int val )
{
    this->atBottom = val == this->verticalScrollBar()->maximum();
}

To copy to clipboard, switch view to plain text mode 

First of all, I'm inserting text using a QTextCursor, not the QTextBrowser's append method. Second, it should only auto-scroll if it was already at the bottom before text was inserted.

2 - I don't quite get your question. The browser doesn't scroll anywhere when you resize it, just show more/less text.

When I make it smaller horizontally, it scrolls up, and when I make it bigger horizontally, it scrolls down.
