Solution: Click Widget - Changing HotRegions at runtime

Hello forum.
I was able to solve the task by myself.

Maybe you like to know the solution:

hotRegionsFrom: rectangles selectorArray: anArray
| anImage index |
"700 @ 500 = static image size"
anImage := Image
extent: 700 @ 500
depth: 1
bitsPerPixel: rectangles size sqrt ceiling
palette: (CoveragePalette maxPixelValue: (rectangles size + 1)).
index := 0.
rectangles do:
[:each |
index := index + 1.
0 to: anImage height - 1
do:
[:height |
0 to: anImage width - 1
do: [:width | ((width @ height) <= each corner
and: [each origin <= (width @ height)])
ifTrue: [anImage atX: width y: height put: index]]]].
^HotRegions selectorArray: anArray mapImage: anImage

postBuildWith: aBuilder
| rectangles clickWidget selectorArray hotRegions |
rectangles := self createRectanglesHere.
selectorArray := self createSelectorArrayHere.
hotRegions := self hotRegionsFrom: rectangles selectorArray: selectorArray.
clickWidget := self widgetAt: #ClickWidget.
clickWidget mappings: hotRegions.

An "[hidden email]" <[hidden email]> Kopie Thema [vwnc] Click Widget - Changing HotRegions at runtime

Hello forum.
I am using a click widget. The left part of the image is static, whereas the right part is dynamic.
Now I like to know: How can I change the HotRegions at runtime?
I don't need something fancy. A simple rectangle shaped region will do the job.
Maybe someone can tell me, how I can create an Image at runtime (extension plus a rectangle box). Maybe this will help also.

Thank you for your answers.

Best regards,
Tom Grünewald
