Re: [Pharo-users] Canvas Transform Goes Haywire if Scaled

by Werner Kassens

Hi Sean, the thing is clipped. as you can see here: morph := Morph new topLeft: 200@400; openInWorld. outputRect := (0@0) corner: (250.0(a)220.0) canvas := Display defaultCanvasClass extent: outputRect extent depth: Display depth. scale := 0.5. t := MorphicTransform offset: outputRect topLeft angle: 0 scale: scale. clipRect := outputRect translateBy: outputRect topLeft negated. canvas transformBy: t clippingTo: clipRect during: [ :aCanvas | aCanvas fullDrawMorph: morph ]. canvas form asMorph openInWindow. werner

Ha ha ha, I was thinking the same thing! But it seems obvious now. I think discoverability + "mouse click on the 5/26 line" (with maybe some kind of icon inviting a click) would help a lot. Regarding shortcuts in general, what is the status of the dream we had when we starting investigating keymapping and friends years ago - "let users totally customize shortcuts"? While it's good to have a reasonable default, no hardcoded solution will make everyone happy... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Spotter-How-to-see-more-beyond-tp4803696p4803921.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

"(morph transformedBy: t)openInWorld." obviously works as expected. but judging from your question, doing a "self transformedBy:" somewhere later in your morphs code wouldnt work? werner

upload your code to smalltalkhub or github and lets take a look at it.

@Trygve I've checked and it doesn't work. I can't even bring the halo on to delete the morph. The debugger keeps popping. Thanks anyway to all Nacho ----- Nacho Smalltalker apprentice.

because right controls the search input box cursor. Maybe a shortcut to switch focus between input search box and the search results panel could cut down the complexity of the shortcuts considerably.

I've been meaning to ask the same question. In light of your answer, Would you consider being able to place the cursor on the line "Classes 5/26" line, and using the standard CMD-Right rather than CMD-Shift-Right. To me that seems to follow the pattern of CMD-Right "opening up" an item. cheers -ben On Thu, Feb 5, 2015 at 2:27 AM, Aliaksei Syrel <alex.syrel(a)gmail.com> wrote: > Hi, > > Select any of that 5 items and use CMD (Alt on windows,linux)+Shift+Right. > Of course shortcuts in spotter are not very obvious, so we are planning to > add hints and have all actions to present as buttons in UI > > Cheers, > Alex > > On Wed, Feb 4, 2015 at 7:11 PM, Sean P.

Re: [Pharo-users] Question on Morphic drawOn: method.

by Trygve Reenskaug

I think you left out a super drawOn: aCanvas in your method. Interesting to hear if this works: drawOn: aCanvas aCanvas borderWidth:10; borderColor: Color green. *super**drawOn: aCanvas.* The rest should work AFAICS, but it could be simplified.
