Coming out of Brush Mode by clicking another button

[KingCode]

Another issue I can't solve, I am in brush mode and I have another button that allows you to come out of brush mode and back into browse mode

choose browse tool

However, the button does not seem to work and stays in brush mode. Because this is for a touch device, I can't use a space bar or enter key to come back out.

Hi again.

Same sort of thing, you have to monitor other LC processes to get out of these things. Put this in the card script:

Code: Select all

on mouseMove
   if the mouseLoc is within the rect of btn "yourButton" and the mouse is down then choose browse tool
end mouseMove

Should work.

Does mouseMove (or touchMove) get sent if the user isn't dragging their finger across the screen? That is, is it sent if the user only taps? I can't remember. If so, then that would be handy in more cases than just this one.

Does mouseMove (or touchMove) get sent if the user isn't dragging their finger across the screen?

No, if the finger is not on the screen, then there is no TOUCH that could be evaluated!
And since there is no MOUSE, "mousemove" will also no get sent!

I Just made a small test (on Mac) with a paint tool/brush:
1. "mousemove" will be sent UNLESS the mouse is DOWN = actually painting!
When mouse is DOWN, there is no mousemove message!
2. "mouseenter", "mouseup" etc. doe NOT work with a paint tool active!
I find this strange to say the least...

All this makes it a bit complicated to control painting on mobile, on the desktop
you can get away with an extra PALETTE window for switching tools.

Any idea how this should work on mobile?

Hi Klaus,

Any idea how this should work on mobile?

Actually it should work as on the desktop:
make a card and an image "myImage" on the card
set the script of the card to

Code: Select all

local sLastLoc

on mouseDown
   put the clickloc into sLastLoc
   if not (sLastLoc is within the rect of image "myImage") then exit mouseDown
   set the pencolor to any item of "red,blue,green,black" 
   set the linesize to 2
   choose  curve tool
   send "doMove" to me in 10 millisec
end mouseDown

on doMove
   if the mouse is up then 
      choose the browse tool
      exit doMove
   else
      lock screen
      put the mouseloc into tLoc
      if sLastLoc is within the rect of image "myImage" And tLoc is within the rect of image "myImage" then
         drag from sLastLoc to tLoc
         put tLoc into sLastLoc
      end if
      unlock screen
      send "doMove" to me in 1 millisec
   end if
end doMove

not tested on mobile

Kind regards
Bernd


Edit: improved code a bit

hi, klaus.
i'm developing a multiplatform app (desktop/mobile) in which user has to use brush/bucket/eraser tool over an image.
and i'm now facing exactly the same issue you described.
i was pretty sure to have found a solution, using the mousemove event to get the "mouse" position (over the image to be painted or not), but, after deeper tests i have to admit my solution is buggy on mobile platform, 'cause of the fancy "mousemove" event.
so, i came here to seek for a solution from masters.
did you get yours, in the meanwhile?

[rmuzzini]

wait… i didn't read with attention last bernd 's post, which offers a nice solution, it seems.

so, probably, something like this could work with brush/eraser:

Code: Select all

    local sLastLoc

    on mouseDown
       put the clickloc into sLastLoc
       if not (sLastLoc is within the rect of image "myImage") OR (the pTool of me is empty) then exit mouseDown //or whatever else, like "dragPictureOverTheScreen", for example
       choose (the pTool of me)
       send "doMove" to me in 10 millisec
    end mouseDown

    on doMove
       if the mouse is up then
          choose the browse tool        
          exit doMove
       else
          lock screen
          put the mouseloc into tLoc
          if sLastLoc is within the rect of image "myImage" And tLoc is within the rect of image "myImage" then
             drag from sLastLoc to tLoc
             put tLoc into sLastLoc
          end if
          unlock screen
          send "doMove" to me in 1 millisec
       end if
    end doMove

//button doBrush script
on mouseUp
	if the hilite of me then
		set the pTool of this cd to empty
	else
		set the pTool of this cd to "brush tool"
	end if
	set the hilite of me to not(the hilite of me)
end mouseUp

but for bucket? i'll do some more tests.

bernd, you're a genius.

following your tips, it works like a charm now. both on desktop and mobile.

for anyone interested i paste here an example of the working code.

Code: Select all

//card script

on mouseDown
   put the clickloc into sLastLoc
   if not (sLastLoc is within the rect of image "picture") OR (the pTool of me is empty) then exit mouseDown //or whatever else, like "dragPictureAroundTheScreen", for example
   choose (the pTool of me)
   send "doMove" to me in 10 millisec
end mouseDown

on doMove
   if the mouse is up then
      choose the browse tool
      exit doMove
   else
      lock screen
      put the mouseloc into tLoc
      if sLastLoc is within the rect of image "picture" AND tLoc is within the rect of image "picture" then
         drag from sLastLoc to tLoc
         put tLoc into sLastLoc
      end if
      unlock screen
      send "doMove" to me in 1 millisec
   end if
end doMove

Hi,

glad you got it working.

bernd, you're a genius

I wouldn't go that far.... just ask people who know me a little better, or better yet don't ask them

Kind regards
Bernd
