Method comparison

by Davide Varvello

In older Pharo versions it was possible to compare two methods selecting them via UI.Â I couldn't find this opportunity in Pharo10, Â so digging into the source code I found SpDiffPresenter, if you pass to it a couple of selectors it can compare them. Example: SpDiffPresenter new showOptions: true; leftText: (MyObject >> #firstSelector) sourceCode; rightText: (MyObject >> #secondSelector) sourceCode; contextClass: True; openÂ CheersDavide

Nontheles, the SpPresenter subclassed objects answer the moveTo: x@y and move the window. Is the window itself considered a widget in this context? Just asking to learn and orient myself. I could more or less do what I originally wanted. A methiod of mine goes thru all opened Survey windows, and reposition themselves in a circle. I like the result , at least as a "variant" of the default positioning, and as an excercise of querying and moving. thanks again and best regards looking forward meeting you soon in Buenos Aires or wherever.

Re: Spec2 - Morph query & move window to another position

by Esteban Lorenzano

I do not understand. you need to position points/morphs in a canvas ? In that case you need a) a canvas and b) the points. This cannot (and should not) be achieved with different widgets (spec) but with just one : a morph there acts as a canvas. So, instead of going to the window of the presenter (which,, by the way, may or may not exist) I would just add a morph, e.g. : (this example is just a script, in real life you would do things differently) presenter := SpPresenter new. presenter layout: (SpBoxLayout newVertical Â Â Â add: (morphPresenter := presenter newMorph); Â Â Â yourself). morph := Morph new color: Color white. morphPresenter morph: morph. morph color: Color white. 1 to: 10 do: [ :index | Â Â Â | pointMorph | Â Â Â pointMorph := Morph new Â Â Â Â Â Â color: Color random; Â Â Â Â Â Â extent: 10@10; Â Â Â Â Â Â yourself. Â Â Â pointMorph position: 300 atRandom @ 200 atRandom. Â Â Â morph addMorph: pointMorph ]. presenter open. this will give you something like this: getting the real size of a window is not really provided by the api except for its initial status (after that, you can suscribe to the resize event if you want to know the new size), but you shouldn't needed thatÂ (and getting the SpWindow which is a morph is not the way to go, since this is not portable). Spec is a framework to make and place **widgets**, as soon as you need something that is not a widget, you need to go to a lower level than it (hence, rendering a morph).

Re: Spec2 - Morph query & move window to another position

by Haroldo Stenger

thanks to HernÃ¡n Morales Durand , he pointed that *CustomerSatisfactionPresenter being a subclass of **SpPresenter* , answers the message *SpPresenter* window which renders a *SpWindowPresenter* object and *SpWindowPresenter* window renders a *SpWindow* object, which answers the message *SpWindow* bounds and *SpWindowPresenter* moveTo: x@y moves the window to the point. any other suggestions are welcome too best regards Haroldo El dom, 16 jun 2024 a la(s) 7:08â¯p.m., Haroldo Stenger ( haroldo.stenger(a)gmail.com) escribiÃ³: > hi all there , I'm playing around with this example from the nice Spec > book, which I try to get right for spec2.

Spec2 - Morph query & move window to another position

by Haroldo Stenger

hi all there , I'm playing around with this example from the nice Spec book, which I try to get right for spec2. That's all right. I modify the example for having two counters, one bound to the class of the Surveys and then one for each survey. That was a good learning experience. Then I added a button to spawn further a Survey which participates of the class-bound count of votes. That's all right too. Then I started to write a method that given a Rectangle, and a number n, gives an array of n Points that are in the enclosed circle of the rectangle, more or less. Waht I want to achieve es that for each added Survey, its Spec2 - Morph window gets positioned in one of these points, but before rendering it, re position all the already existing Spec2 - Morphs Survey windows in the rest of the points of the array (being n the total number of Surveys after adding one). I'm facing two challenges: (a) getting the list of current positions of Spec2 - Morph Surveys already existing. (b) moving a Spec2 - Morph window to another position. I'm pretty stuck trying to make my way for this two goals, so any kind help will be really welcome. Yo can import the files into a Pharo12 image with the File manager, then Changelist Browser and selecting all the lines and "file in". thanks in advance ! Haroldo
