Dear Markus, thanks for the 'extended' answer. Unfortunately I could not follow your description. I did the following: 1. I worked with Squeakland image 3.8-05 latest update: #531 2. I drew an 'Ellipse' and filled it (that should become my 'button') 3. The balloon of the 'color-pipette-halo' says: 'Repaint'. Shift-Click: Back in the paint tool. Ctrl-Click: I get a menu (must be the same for every halo) that lists: grab copy to paste buffer delete . . . debug But neither a button, nor an entry 'button'.

Assuming you are using an up-to-date squeakland-image click on the color-pipette-halo of your morph (might be chift-click, depends on the morph, haven't explored the differences yet) and then the button labeled "button" on the bottom. ;-) There you can add a label. You can set the text of the label by opening a viewer on it. Go to the "text"-category and type in your label in the characters setter. (It is a bit strange that one cannot change the label in the dialog directly). From there you can also drag put the label setter for reasons described in my last mail below. 2.) Take out a text morph of the supplies-flap, embed it into your button, and proceed as above. The advantage of doing so is that you can change the text and the font directly. Cheers, Markus p.s. I actually found out about the first option only last week, after sending below mail.

RE : [Squeakland] Little problem (update)

Hi Kelly It is not a good Idea to have StartScript square in the script square itself If you start the script clicking on the watch, this will start the process and the first line (pencil startScript square ) will do nothing since the script is allready ticking. This works .... But ... If you are using either the yellow exclamation dot or the buton to fire the script square,. the script is executed, the first line starts the script ticking and the rest of the script attempt to move the pencil too, the pencil is moved twice, one by the comand in the script square and one by the command in the script started by the command startScript. This is about simultaneous, the for the two other sides, they are made by commands in scripts 'square' fired at the right time by the ticking status of the script, therfore each at the correct time. The good programing is to use two scripts one for doing things just like square without the first line , and one to star this script , this one being fired by a button. It's a good idea too to put 0 into count in this script before the line startScript. So just start a new script draging pencil compt <- 0 and then drag pencil startScript square from the script square and put it in the new script, call this script startSquare and get a button to fire it . Do the same with the other shapes.

The batch pen trails option was on for my playfield causing some of the lines not do be shown. But I am still not sure why this only happened when I used a button to fire the script. However I now have another problem. When I fire the script with a button it draws the first two sides at the same time and then draws the others. I want to be able to see all of the lines being drawn (like it does when you start it manually). Is this normal? Or is there something else I need to do, that I have not yet discovered?

Test a random tile.
by Blake 02 Mar '06

I know can do this indirectly by assigning a random value to a variable and then testing it, but is there any way to test a random tile directly? (You get no green assignment arrow with the tile and I don't see how to add one.) ===Blake===

Set transparent color.
by Blake 02 Mar '06

Hey, Squeaklanders-- I've got graphics from an external source that I'm importing into Etoys. However, they have a white background which is coming through rather than being treated as transparent. I've resolved this by saving them as GIFs and setting the transparent color. But it'd be cool to be able to fix that inside of Squeak. So...is it?<s> ===Blake===

Label of a button Was: RE: newbie(ish) question (buttons)
by Hübner, Uwe 01 Mar '06

Hi Squeakers. I wonder if I've missed something. How can I create a 'Label' of a button? (I think a 'button' is something I've drawn and now tell it to act upon mouse-down, isn't it?) If a Label means text embedded into a drawing, how can I change that text?

Little Problem
by Kelly 01 Mar '06

01 Mar '06

Hey there, I have something that is just baffling me. Maybe it is just due to lack of experience but I hope someone can help me out. I have a script to draw a square. It works fine if I start it myself by setting it to ticking. However I have created a button to fire the script and when I press it is draws a triangle!! I have been trying to work out what I have been doing wrong for hours and I am just baffled. Have I made some rookie mistake?? Thanks Regards Kelly
