Morph Drop Shadows

Can I change the pick up a morph so that it doesn't have a shadow? I tried in the morph menu to drop shadow: show shadow, but this doesn't work. It doesn't affect the morph whether the show shadow is checked or not. dhs _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |

For drop shadow to be visible, make sure the drop shadow color is different from the background and the offset is non-zero. The drop shadow (in halo menu) is different from the temporary shadow that appears when you 'pick' the morph. Regards ..

It is the temporary shadow that appears when I pick the morph that I want to eliminate. I am using 3.9 although I can switch to an older version if it would help. dhs On 20 May 2007, at 13:23, subbukk wrote: > On Sunday 20 May 2007 10:07 pm, David H.

You can't control this from the halo menu. It is a built-in behavior for all Morphs. I am not aware of any preference setting to eliminate this pick up shadow. You will have to patch the Morph classes to eliminate it. Sorry ..

The Hand draws a shadow of all morphs it is holding. You could
implement the dragging of your morphs yourself and not leave that to HandMorph. Or hack HandMorph>>fullDrawOn: method to not draw the shadow (possibly in a subclass). May I ask what you need this for? - Bert - On May 20, 2007, at 19:38 , David H. Shanabrook wrote: > Subbu > > It is the temporary shadow that appears when I pick the morph that > I want to eliminate.

I am experimenting with geometry tutors, such as pentominos. when
trying to fit shapes precisely together the shadow is very disturbing, it is hard to know what is the shadow and what is the shape, especially for kids. dhs On 20 May 2007, at 14:51, Bert Freudenberg wrote: > The Hand draws a shadow of all morphs it is holding.

In that case it's surely simplest to add the mouse handling to your
pentomino tiles. - Bert - On May 20, 2007, at 21:01 , David H.

When I want to remove the drag-shadow from Morphs, I often use something like the following methods (implemented on my Morph subclass): fullDrawOn: aCanvas aCanvas isShadowDrawing ifTrue: [^ self]. super fullDrawOn: aCanvas. #fullDrawOn: is sent to a Morph to ask it to draw itself, its border, and its submorphs. The Hand uses it to draw a shadow copy of the Morph. This method says, if that's what's going on, don't draw anything (therefore preventing any shadow from being shown). wantsToBeCachedByHand ^ false This message is also sent during shadow drawing. It seems to be necessary to prevent shadows from being drawn, but I'm afraid I have forgotten why! and I'm not sure I have a chance to track it down right now. (I almost held off from posting this because of that, but I thought it would be better to offer the advice and leave an exercise for the reader. :) Note that the shadow does serve at least one important purpose. In the default mouse handling, clicking on a Morph picks it up, and one must click the mouse again to drop the Morph. It can be confusing to have a Morph "stuck" to the hand without any visual indication. I often make a simple mouse override to fix this too, if I am not doing any more specialized mouse handling on my own. Here is what I do: handlesMouseDown: evt ^ true This tells Morphic that a particular Morph wants to receive mouse events. mouseDown: evt evt hand waitForClicksOrDrag: self event: evt selectors: #( #click: #doubleClick: #doubleClickTimeout: #startDrag:) threshold: 0 This message is sent on mouse down. The method here tells the Hand to parse upcoming mouse events, and decide whether a click, double click, or drag might be happening. The threshold of "0" says to interpret any mouse movement at all as a drag. (There is a simpler variant of #waitForClicksOrDrag... that defaults that to 10, which I find to be too unresponsive.) startDrag: evt evt hand grabMorph: self. This is called when the Hand detects a drag, after the "wait" message from above. The method just tells the hand to pick up this Morph. Of course I'm sure there must be some flag that does the same thing! ;) If I am writing a system with many Morphs like this, I of course put all of this code in a superclass to avoid clutter. Hope this helps, Benjamin Schroeder _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |

I found if I just change the value of HandMorph dropShadows shadowOffset from 6@8 to 0@0 this eliminates the drop shadows. For morphs with opacity less than 1.0 the morph turns opaque when clicked on; which helps with noticing the object is picked. Would this be a variable which could be set in Preferences? I think others must also find drop shadows make positioning morphs difficult in some circumstances.

[Newbies] Morph Drop Shadows
HI David H. Shanabrook, As Bert says the trick is to move the morph w/o lifting it. One general way to do that with any morph is the brown halo handle. The other is to create a morph that behaves the way you want. I had started some work which I had hope to apply to moving block puzzles. I wrote a little about it Here: http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-May/116371.html And posted my work in progress code to bob's super swiki http://209.143.91.36/super/728 MovingPiece-wiz The codes in the form of a 3dot9 project. Load the project and look at the change set for it. Also earlier related work on puzzleboards modified a pasteup morph to prevent overlapping pieces: http://209.143.91.36/super/634 Puzzleboards The code is in both project form (for an old 3.7 squeak) and as change sets. The change set should work in 3.9 and probably a recent 3.8 (if they fixed the bug mentioned) You will need to adapt it to apply to pentomino's Hth.
