Can't put my finger on what triggers the view be rendered with normal sized (doesn't fit the page) vs zoomed out (fits the page) Yes, you can have a look at Roassal2GT-Glamour-Roassal-Interaction Here are some examples. The default behavior is obtained by: -=-=-=-=-=-=-=-=-= b := RTMondrian new. b nodes: (1 to: 100). b layout grid. b view @ RTResizeableViewContextInteraction. b -=-=-=-=-=-=-=-=-= If you wish to not have any resize, then you can do: -=-=-=-=-=-=-=-=-= b := RTMondrian new. b nodes: (1 to: 100). b layout grid. b view @ RTEmptyViewContextInteraction. b -=-=-=-=-=-=-=-=-= The code is not clean at all. This is due to the limitation of GTInspector. Help is welcome on that front!

Re: [Pharo-users] RTDoubleScrollBar is not rendered properly in html

by Andrei Stebakov

Hi Alexandre Thank you for your suggestion! I also stumbled upon RTHorizontalTreeLayout that works much better in terms of having more compact representation. What I found out though is that when I inspect the view sometimes it displays all the ellipses with their specified sizes and sometimes it shrinks the view to fit in the viewable area.

Re: [Pharo-users] Zoom x-axis in RTGrapher?

Hi Alistair! Yes, this is something we thought about some times ago.

Re: [Pharo-users] Looking for small boards and tiny computers which can run Pharo

by Jonathan van Alteren

No, I haven't done much with Pharo yet, least of all adapt it to run on an IoT device ;-) I'm interested though, but it will take me considerable time to reach that level of experience. I've got a BeagleBone Black running some Node.js things though, and would love to add Pharo to the mix. I like the BB better than the Raspberry Pi because it has 4Gb MMC on board, instead of having to rely on an SD card (which can get corrupt in case of power loss). I will try Pharo IoT in time, either on RPi or BB. Thanks! Jonathan -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Thanks! Offhand idea... Now that we are managing Pharo-Image from git, perhaps it would make sense to move PharoLauncher first-level entry configuration to git? Also perhaps Pharo Catalog can be managed in same way (if its not already). cheers -ben (hic!)

Zoom x-axis in RTGrapher?

by Alistair Grant

Hi Everyone, I'm using RTGrapher to display a simple line graph where the x-axis has values from roughly 0 to 500,000 and the y-axis from 0 to 20. What I'd like to be able to do is to zoom in just the x-axis, i.e. instead of displaying the entire 0 to 500,000 range, be able to narrow it down in stages, to, e.g. 430,000 to 431,000. The y-axis would be unchanged, i.e. still 0 to 20. Ideally I could then scroll left and right along the x-axis. I can create a Spec widget with buttons to redraw the graph, but was wondering if there was a better way. Thanks, Alistair

Detecting "window closed" for modal Spec window

by Peter UhnÃ¡k

Hi, is it possible to detect when a modal window was closed in Spec? I can do the following window := TextModel new openWithSpec. window window announcer when: WindowClosed do: [ self inform: 'window closed' ]. But when I make the window modal it is no longer being announced window := TextModel new openWithSpec. window modalRelativeTo: self currentWorld. window window announcer when: WindowClosed do: [ self inform: 'window closed' ]. Is there some other way how I can achieve this? Thanks, Peter
