Is there a tandard way to attach context menus
by Herbert König 04 Nov '11

04 Nov '11

Hello all, is there a standard way to attach a context menu to a morph? It's fairly easy to do by checking for yellowButtonPressed and manually firing up a MenuMorph. But it is sufficient to implement #addCustomMenuItems:hand: to get an enhanced Halo menu while #addYellowButtonMenuItemsTo:event: and #hasYellowButtonMenu don't help. So is there a predefined way without everybody doing his own? Thanks, Herbert mailto:herbertkoenig@gmx.net

Omnibrowser help
by Rob Rothwell 14 Aug '11

14 Aug '11

Are there some tips/documentation somewhere on getting the most out of the OmniBrowser? The MulitpleSelection browser looks interesting (sort of like the tabbed browser in VisualWorks), but I don't quite understand its behaviour and what method it decides to show in which pane when you move around or save changes. On the same topic, can anyone point me toward how I could add a new item to the class context menu in the OmniBrowser? I want to add a new template selection menu item (like "new class template" and "new trait template") because I have created a method that creates TWO classes at the same time for an Aida application (A domain model class AND its associated WebApp class). Thanks, Rob Rothwell

Keyboard shortcuts in squeak (pharo)
by sserre 03 Jan '11

03 Jan '11

Hello, Normaly, I use vim or emacs and find usefull to not use the mouse when I code. I did not find any reference to the shortcuts used to manage windows, class browther ect, in Pharo. It should exist, some of them are show when I right clic (save, doit, printit...), but google did not help me to find more. Some shortcuts that I will find very usefull migth permit: - to change the window focus (change windows) - move between the parts of the class browser (packages, classes[instaces, ?, class, hierarchy, variables...], categories, methods, edition), - close tools, open tools (class browser, transcript, workspace...) There maybe exist an alternative class browser/editor that will permit such things? Shortly, does anyone have the same horror of rats than me :), and what solutions have you found? Thanks in advance.

Wait for an external app
by Sean P. DeNigris 13 Nov '10

13 Nov '10

While controlling QuickTime Player via Applescript from within the image, I want to play a CD track until it reaches a certain point. QTP does not expose "playTo: aPosition" functionality, so I'm polling the track position until the time is reached. I don't want to lock up Morphic, so I'm doing this in another thread. The following works, but I've never used threads before and wanted to get opinions. What do you think? cd play. [ [ cd position < endTime ] whileTrue: [ Processor yield ]. cd pause ] fork. * "cd position" gets the track position via Applescript * endTime is a variable holding the time to play until Sean -- View this message in context: http://forum.world.st/Wait-for-an-external-app-tp3030911p3030911.html Sent from the Squeak - Beginners mailing list archive at Nabble.com.

How to write Floats to a file. Is using at:1 and at: 2 the only method of doing it. If so, why there is no support for Float writing in streams?

Modal UI
by Sean P. DeNigris 08 Nov '10

08 Nov '10

In the process of my app's execution, it needs to put up a UI, and pause until the UI returns an object (only this piece of code needs to pause, the rest of the world can keep going). I was thinking of using forks, but FillInTheBlankMorph seems to manually drive the world's doOneCycle while it waits (seems ugly and a little too controlling). What would be the best way? Thanks.
