Using an HTML table in a tooltip, then there is extra space added between the bottom of the table and the end of the tooltip box

When using an HTML table in a tooltip, then there is extra space added between the bottom of the table and the bottom of the tooltip box. This only happens if a column in the table contains a relatively long string.

The following example reproduces the problem. Note that only the tool tip with the long string ("This is a long name 1") exhibits the problem. The tool tip with the shorter string ("Name 1") does not have this issue.

#include <QtGui>

class MainWindow : public QMainWindow
{

public:
MainWindow(QWidget *parent = 0)
: QMainWindow(parent)

{ QWidget *w = new QWidget( this ) ; QVBoxLayout *l = new QVBoxLayout( w ) ; QLabel *lab = new QLabel( "This label has a tooltip with long names" ) ; lab->setTextFormat( Qt::RichText ); lab->setToolTip( this->tooltip( true ) ) ; l->addWidget( lab ) ; lab = new QLabel( "This label has a tooltip with short names" ) ; lab->setTextFormat( Qt::RichText ); lab->setToolTip( this->tooltip( false ) ) ; l->addWidget( lab ) ; setCentralWidget( w ) ; }

QString tooltip( bool long_names )

{ QTextDocument doc ; QTextCursor cursor( &doc ) ; QTextTable *table ; QTextTableFormat format_table ; QTextTableCell cell ; QTextCursor cellCursor ; table = cursor.insertTable( 2, 2 ) ; format_table.setCellSpacing( 0 ) ; format_table.setCellPadding( 3 ) ; format_table.setBorder( 1 ) ; table->setFormat( format_table ) ; cell = table->cellAt( 0, 0 ) ; cellCursor = cell.firstCursorPosition(); cellCursor.insertText( ( long_names == true ) ? "This is a long name 1" : "Name 1" ) ; cell = table->cellAt( 0, 1 ) ; cellCursor = cell.firstCursorPosition(); cellCursor.insertText( "Value 1" ) ; cell = table->cellAt( 1, 0 ) ; cellCursor = cell.firstCursorPosition(); cellCursor.insertText( ( long_names == true ) ? "This is a long name 2" : "Name 2" ) ; cell = table->cellAt( 1, 1 ) ; cellCursor = cell.firstCursorPosition(); cellCursor.insertText( "Value 2" ) ; return( doc.toHtml() ) ; }

} ;
