Bruschetta

Hello guys,
i have a set of images, all of the same size (height and width), and for each image i have a set of coordinates (x,y) rapresenting interactive points i have to draw on the selected image.

@Bruschetta Which way are you preferring ? Qt Widgets or QML/QtQuick ?

Qt Widgets

I would like to use Qt Widgets

@Bruschetta Ok. What do you mean by interactive here ? Are these just static or movable/draggable ?

@p3c0
The buttons must be static , but clickable to trigger some action (in my case select a column of a TableView).

@Bruschetta The best way would be to use the Graphics View Framework. Have a look at these classes.
For eg. To add the image you can use QGraphicsScene and use addPixmap to draw the image.
To draw the circles you can use QGraphicsEllipseItem. To make them clickable you can subclass it and re-implement mouseReleaseEvent and emit a signal from it.
