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

Yes, by using flaps - these are global containers. For instance, the flap that contains Paint tool, Rectangle, Ellipse etc is a flag. Just drag your text object into this flap, switch to the target project and then pick and drop the text into the opened project. If you need specific help, please include the version of your Squeak/Etoys. HTH .. Subbu

Hello, Is there a way to move an object from one project into another project? For instance when I create a text object in the main world screen, I would like to be able to move it into a child object or the other way around. Thank you.

A Cuis Bug

Here's the error I get frequently when copying text to a browser. I've learned if I click "Proceed" it continues fine. But it's odd to even get the error. How can it be fixed? This is a copy of the debug log file.

Easy To Reproduce Bug
by Overcomer Man 13 Sep '11

13 Sep '11

Since I don't know how to get past the wrench in copying a debug, here's an easy recipe to reproduce the error. 1. Open up a fresh image of Cuis, and a fresh browser. 2. Add a dummy category and class. 3. Add a test method to return a string. 3. Add text to the string before accepting it. 4. Repeat 3 or 4 times then an error will appear: 'Instances of UndefinedObject are not indexable' 5. Clicking on the text pane will produce additional errors with the same message. This appears to be semi-random. I have had it happen without the repeats in step 4. It sometimes goes away for a while. To insure reproducability, I copied text each time from http://www.biblegateway.com/passage/?search=Matthew+1&version=KJV In my newbie opinion, it looks like it must happen to people frequently. It also happens in Workspace.

> Anyway, if you pull the halo on the debugger, you should be able to click the wrench, which will give you an inspector that you can use to drill down into the actual stack trace. Too bad the drill down process wasn't explained. Now what does one do to get the stack copied?
