==Chapter 5 - Apply mouse selection==
//[[user:StPendl|1319905735]]//
Now we are ready to start implementing the initial request to enable color selection by clicking the color boxes instead of the radio buttons.
We only have to apply the same naming convention to the graphics boxes used to display the tolerance colors to be able to use a unified mouse event handler.
[[code format="lb"]]
graphicbox #w.Gold4 , 410, 40,30,30
graphicbox #w.Silver4, 410, 80,30,30
graphicbox #w.None4 , 410,120,30,30
[[code]]
Now we assign the mouse event handlers to all the graphics boxes, which is a piece of cake now, since we use loops to apply changes:
[[code format="lb"]]
FOR Band = 1 to 3
FOR Color = 1 to 10
Handle$ = "#w."; Colors$(Color,1); Band
#Handle$ "cls;down;fill "; Colors$(Color,2); ";flush"
#Handle$ "when leftButtonUp MouseClick"
NEXT
NEXT
FOR Tolerance = 1 to 3
Handle$ = "#w."; Tolerances$(Tolerance,1); 4
#Handle$ "cls;down;fill "; Tolerances$(Tolerance,2); ";flush"
#Handle$ "when leftButtonUp MouseClick"
NEXT
[[code]]
Finally we just need to add the initial display and the mouse event handler.
[[code format="lb"]]
' apply initial settings
call MouseClick "#w.Black1", 0, 0
call MouseClick "#w.Black2", 0, 0
call MouseClick "#w.Black3", 0, 0
call MouseClick "#w.None4", 0, 0
[none]
WAIT
[quit]
close #w
END
SUB MouseClick Handle$, PosX, PosY
RBhandle$ = Left$(Handle$, Len(Handle$)-1); "r"; Right$(Handle$, 1)
#RBhandle$ "set"
call SetBandValue RBhandle$
END SUB
[[code]]
The complete code now looks like this.
