Re: [Pharo-users] Spotter: How to see more beyond #/##

by Tudor Girba

Hi, Switching is costly, and we went to great lengths to not have any switching between the text and the list in spotter. This won't change :). But, there will likely be some way to switch to the preview, but this is still a work in progress.

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.
