QTextCursor Find QTextTable ok and !QTextImageFormat

[patrik08]

I build a small xhtml editor.... start point is QTextEdit

to discovery the objekt QTextTable is easy and i can make context menu to chance cellpadding spacing background color widht and so....

QTextTable * QTextCursor::currentTable () const
Returns a pointer to the current table if the cursor position() is inside a block that is part of a table; otherwise returns 0.


Now i like to discovery QTextImageFormat objekt to chance hight widht name ... how i find a pointer ?...

/* QTextEdit *html_area; */
connect(html_area, SIGNAL(cursorPositionChanged()),this , SLOT(WakeUpCursor()));
 
void  Html_Editor::WakeUpCursor()
{
    QTextCursor findercursor(html_area->textCursor());
    if (!findercursor.isNull()) {
        /* discovery if a table is selected to display CustomContextMenu start */
        if (findercursor.currentTable()) {  /* !=0 */
            worktable = true;
            existingtable = findercursor.currentTable();   /* (header) QTextTable *existingtable; */
            SetupTable();
            html_area->setContextMenuPolicy( Qt::CustomContextMenu );
            connect(html_area , SIGNAL( customContextMenuRequested( const QPoint & ) ), this, SLOT( TableContexMenu() ) );
        }  else {
            ResetTableContex();    /* disconnect remove table context menu and work table false */    
        }
        /* discovery if a table is selected to display CustomContextMenu end */
 
        /* discovery??  #include <QTextImageFormat>*/  
    }
 
}

/* QTextEdit *html_area; */
connect(html_area, SIGNAL(cursorPositionChanged()),this , SLOT(WakeUpCursor()));

void  Html_Editor::WakeUpCursor()
{
    QTextCursor findercursor(html_area->textCursor());
    if (!findercursor.isNull()) {
        /* discovery if a table is selected to display CustomContextMenu start */
        if (findercursor.currentTable()) {  /* !=0 */
            worktable = true;
            existingtable = findercursor.currentTable();   /* (header) QTextTable *existingtable; */
            SetupTable();
            html_area->setContextMenuPolicy( Qt::CustomContextMenu );
            connect(html_area , SIGNAL( customContextMenuRequested( const QPoint & ) ), this, SLOT( TableContexMenu() ) );
        }  else {
            ResetTableContex();    /* disconnect remove table context menu and work table false */    
        }
        /* discovery if a table is selected to display CustomContextMenu end */
        
        /* discovery??  #include <QTextImageFormat>*/  
    }

    QTextCursor findercursor(html_area->textCursor());
    if (!findercursor.isNull()) {
        /* discovery if a table is selected to display CustomContextMenu start */
        if (findercursor.currentTable()) {  /* !=0 */
            worktable = true;
            existingtable = findercursor.currentTable();   /* (header) QTextTable *existingtable; */
            SetupTable();
            html_area->setContextMenuPolicy( Qt::CustomContextMenu );

        /* discovery if a table is selected to display CustomContextMenu end */
        /* discovery ImageFormat  selected to display CustomContextMenu start */
        if (findercursor.currentFrame()) {

             /* blockpiece = findercursor.currentFrame();   QTextFrame *blockpiece; */
             QTextImageFormat newImageFormat = findercursor.charFormat().toImageFormat();
             if (newImageFormat.isValid()) {
