Hi!
If have a canvas(view) with some items of sprites and text (CanvasSprite
and CanvasText).
How can I change the text? With
QCanvasItemList list = canvas()->collisions(e->pos());
if ( !list.isEmpty() ) {
QCanvasItem* item = list.first();
// some code
}
I can found and select the item touched by the mouse. But now I only have
access to the CanvasItem Members like move. But I need to access text()
and setText(), which is no element of QCanvasItem.
To store some data with the sprite items I've written a subclass of
QCanvasSprite, called MyCanvasSprite. Now I con store and read some
informations like name or numbers to sprites.
But I habe the same problem to access them like to access the text on
text items.
Any ideas to slove this problems (sorry, I'm a newbie on C++ and Qt)?
Frank
