Hi,
Hi Philipp,
First, sorry for the delay, and the dumb title ... I modified it,
say, more accurately

Doing that, I can display a help string when the mouse cursor
rolls over
application icons. That's nice, but I'd like to display the text in a
given area, and I don't find a method doing that (at least in
toolbox.hxx).
Is there one I missed, or, shall I implement a new one, passing a
given
rectangle as argument (e.g.) ? (I'll reverse the code, of course)
no, there is no such method.
Ok, then in the Toolbox class, I found a SetItemText method, currently :
{
USHORT nPos = GetItemPos( nItemId );
if ( nPos != TOOLBOX_ITEM_NOTFOUND )
{
ImplToolItem* pItem = &mpData->m_aItems[nPos];
// Nur wenn alles berechnet ist, mehr Aufwand treiben
if ( !mbCalc &&
((meButtonType != BUTTON_SYMBOL) || !pItem->maImage) )
{
long nOldWidth = GetCtrlTextWidth( pItem->maText );
pItem->maText = ImplConvertMenuString( rText );
mpData->ImplClearLayoutData();
if ( nOldWidth != GetCtrlTextWidth( pItem->maText ) )
ImplInvalidate( TRUE );
else
ImplUpdateItem( nPos );
}
else
pItem->maText = ImplConvertMenuString( rText );
// Notify button changed event to prepare accessibility bridge
ImplCallEventListeners( VCLEVENT_TOOLBOX_BUTTONSTATECHANGED,
reinterpret_cast< void* >( nPos ) );
// Notify
ImplCallEventListeners( VCLEVENT_TOOLBOX_ITEMTEXTCHANGED,
reinterpret_cast< void* >( nPos ) );
}
}
The idea consist in an overloaded Toolbox::SetItemText() with a new
itemId, linked to the rectangle where we'd like to draw the help
text. e.g. add :
void ToolBox::SetItemText( USHORT nItemId, const XubString& rText,
USHORT nTargetRectItemId )
{
/* inside the method, do :
1) get the nPos of the first itemId: USHORT nPos = GetItemPos
( nItemId );
2) Verify the itemId is valid
if ( nPos != TOOLBOX_ITEM_NOTFOUND )
{
// do the right work
}
else do nothing
3) if nPos does match with a valid item,
create the pItem as previously : ImplToolItem* pItem = &mpData-
>m_aItems[nPos];
4) do the same job with the text (like in the not overloaded method)
5) get the nPosTargetRect of the target rectangle
6) if ok, ImplUpdateItem( nPosTargetRect ); // nPosTargetRect is a
fixed value
This is the idea: draw the text at the right location (the target
rectangle for instance)
7) .. and so on for the rest (like in the not overloaded method)
}
*/
The counterpart is, the nTargetRectItemId must be defined, and its
location defined too.
What do you think ?
Thanks,
Eric
