Roassal MouseMove over element bug

Hi,

I've encountered a bug with TRMouseMove.

When registered on canvas it doesn't get fired when mouse is over an element which has any callback registered.

In TRMorph>>rtMouseMoving:

line shape := self shapeWithActionForPositionInPixels: relativePosition. doesn't respect what kind of event is actually registered to the shape - so if I register TRMouseClick on a box, TRMouseMove on canvas will not work.

I would expect the event to always get fired for canvas.

Peter

demo:

------------

view := RTView new.

lbl := RTLabel new elementOn: 'position'.

view add: lbl.

badBox := RTBox new size: 50; color: Color red; element.

badBox translateBy: -50 @ -50.

view add: badBox.

goodBox := RTBox new size: 50; color: Color green; element.

goodBox translateBy: 50 @ -50.

view add: goodBox.

badBox

when: TRMouseClick

do: [ ].

view

when:TRMouseMove

do: [ :evt |

lbl shape text: (view canvas camera fromPixelToSpace: evt position) printString. lbl update.

view signalUpdate ].

view open.

Re: Roassal MouseMove over element bug

Hi Peter!

This has been a known bug for a long time.

Your mail motivated me to fix it.

You need to update Roassal :-)

Cheers,

Alexandre
