We have now moved the accept and cancel to the contextual menu for now. However, the longer term goal is to change this pattern. Here is a longer explanation. We think of the IDE like terms an object-oriented system built using a language. From this point of view, an action is put in the context that provides enough information to trigger it. So, for actions that do not rely on the selection, or on the cursor position, we can safely put them in the toolbar of the presentation. For global actions (like refreshing the whole inspector), we put them all the way in the title bar. For example: - "Do Itâ depends on the selection or cursor, and thus it is added to the context menu - âAccept" is not specific to the current location of the cursor or of the selection and can be made presentation specific (added to the toolbar of the presentation). - Switching the whole debugger to a âBytecodeâ one is global for the whole debugger, and it is added to the top of the visual hierarchy. This choice also documents the scope of an action. For example, imagine having a global toolbar with actions that only do something in a certain pane (out of possible many). How will you know before triggering what is the effect going to be? But, if you always put the action to the scope that it affects, there is a more clear connection because cause and effect. And there is yet another advantage. When you stick with this design, you get potentially reusable components. This does require some getting used to. And this design will not necessarily work for general UIs. But, an IDE is not a general UI. It is made for programmers, and in our case, it is made for object-oriented programmers, and we can use the abilities of such programmers in our designs. Does this explanation make more sense?

Nice, but: It's not an obvious, standard UI behaviour In a complex class, you still need to hunt through the list to find the first local variable, that's frustrating. You cannot even use incremental search there. That should probably be a wishlist item on the bug tracker. > >> Also, could the scroll position in the variable be preserved while stepping? > > I am not sure what you refer to. The currently selected variable is preserved both when you step, and it is even preserved when you switch back and forth through the stack. > > What am I missing? The selected variable is preserved, but if ones scroll the variable list using the mouse wheel, the scroll position changes but not the selection. Stepping resets the scroll position to show the selected variable, which is "self" by default. I would like the scroll position for the variable list to be remembered by the debugger in each object. Or maybe the right granularity is concrete class, I am not sure. >> Unfortunately, Pharo does not appear to receive ctrl-tab keydown events, so I need to reach for the mouse to move the focus out of any text areaâ¦ > > Indeed, this does not work. I already reported that before on the mailing list, and I have tracked it down to ctrl-tab keydown not even reaching Sensor. The corresponding keyup are correctly detected. So I guess it might be a vm issue. I should probably file a proper bug report.

Seems easier to just parse an external file to me. Well, for me, on a pure technical basis, no. - It adds one failure point: reading one more file at startup. - It adds management issues: slight version differences in an external libs may force me to add context-dependent json file loading. > I like the use of Smalltalk for eg user interface opening code where > - we want a UI construction tool to edit an e excitable > representation of the interface - there is only one version of the UI > method > > But with these interface descriptions we could easily end up with a > 32-bit and a 64-bit version for every UNIX variant plus Mac OS and > Windows.

You have the same complexity, either in a json or in an init file; and the same level of customization or even more flexibility (you can decide to set those initialisation methods in different packages, and have the flexibility to slice / share the way you like... 64bits / 32bits, 64bits ARM + MIPS are the same except one constant, etc...). It's a bit like dealing with those configure scripts: in C, if you really want multiplatform support, you write #ifdef macros and shell scripts to query the build platform for you... I just prefer to do it in Smalltalk if I have to. But I guess that I could still do it by hacking the FFI layer anyway :) And I'd be happy to see a system modeling layer in Smalltalk (one which knows how to query hardware/software capabilities at startup) since it opens up yet unforeseen possibilities (switching on an OpenCL acceleration layer on supported platforms with the right driver version?).
