I have typed some keywords in the forum but the raised topics seems to not address my question.
When I click on an item, I would like to
- display an overlay or a popup but not a windowed-popup from the browser but within the main window.
- to choose the width and height of the overlay (a rectangle in the middle of the window)
- to add a close button on this overlay
- it contains an image that is hosted online
- the only possible action from the user is to close the overlay and it is then not possible to do something else in the scene
- when the user clicks on the close button, the overlay disappears and we see again the main scene
How can we do that?
How can we specify a link for the image that is relative and not absolute from the server? (…\ ?)
