displayin' many images on a scence

[peace_comp]

Hi..
I would like to know if there is way to display many images in a same graphicsScene..
as a grid that contains images ..each one besides the other :


*****************
* pic1 * pic3 *
*****************
* pic2 * pic4 *
*****************
I guess it could be done via rect .. but how can I define n rect one beides the other as grid ?!!

NB> I need that to zoom on a map ..I will display first only 4x4 images .. then depending on the zoom (in or out) I may display or hide other images...

if someone has an idea !!
thanks

why do you need GraphicsScene for such functionality ??
You can very well do it with layouts and labels. Except for zoom part, it will little more effort i guess.

Without graphicsscene -
You can display images in a QLabel objects, and arrange the labels using QGridLayout. For zooming in and out, u can change the size of Qlabel and adjust the grid layout accordingly.


With graphicsscene-
u need to manipulate the positions urself, because u gonna be placing items in the scene.
For this a a simple calculation can help-
nth_item->setPos((n/no_of_columns)*height , (n-1)*width);

am not sure if this will work, but i hope u got the idea. In this scene case, zooming will zoom into the scene, it wont arrange the images for u.


Depending on the functionality u want to achieve, u can choose either of the solution

Also u can refer puzzles examples in Qt demo, it may help u
