Morphic
by Peter Schuller 23 Dec '00

23 Dec '00

Hello, I realize I have just been asking questions since I joined this group. Hopefully I will eventually be knowledgeable enough to constribute in the form of *answering* some. But for now, I have yet another question: Is there a tutorial/overview/howto for Morphic that covers more than the extreme basics? I don't have a problem understanding the basics concepts, but I am still suffering from being "lost" in the API. Probably because I'm mostly coming from a Swing/Qt background and things are obviously done quit differently in Morphic. The only one I've found that actually introduces you to the API is John Maloney's "Fun with the Morphic Graphics System" (referenced at http://minnow.cc.gatech.edu/squeak/30), which is good at what is does, but is limited in scope and seems to be geared towards those that aren't familiar with even the Squeak browser yet. I'm looking for something to accelerate the initial learning process; i.e. point out how to do some common stuff so that I can a better "feel" for it. Like creating windows, managing menus and component layouts. Just now I was trying fooling around with menus and the SystemWindow. I was not able to figoure out how to add menus to a SystemWindow (or if there is even any special support for such actions). I'm sure I'll get it straightened out after browsing the API some more, but hence my desire for a hands-on tutorial just to get a feel for the most common things...

Hi Karl, There is some version checking and there used to be more, but in an effort to be more swiki-like, we dispensed with some of the warnings, which could get kind of complicated. I think that as we see people using projects for real things, we will probably develop some alternatives in this area. I loaded your ColorChanger and it works fine. Cheers, Bob

Hi Karl, This is an area that has not gotten as much attention as it deserves. I have just put together an experiment that seems to work and I welcome all to try it and see if it satisfies the needs in this area. On Bobs SuperSwiki, there is a project "btest" that contains: - An inspector on an instance of a class not defined in a normal image (BobTest). - A workspace containing the code needed to allow you to publish such projects. Things to verify (they work for me, but perhaps I have overlooked something): - Does the project load without error? - Does the inspector show you the three instance variables? - If you follow the instructions in the change set in the workspace (reprinted below), are you able to publish such projects? Cheers, Bob --- from the preamble to the change set --- An EXPERIMENTAL change set that offers the option of also filing out the project change set when publishing a project. Selecting this option will permit a project that contains classes not defined in a normal image to be read in successfully. Steps to publish such a project: - File in this change set. It is experimental, so you may not want to save the image. - Go to the project you intend to publish. - Verify that the project change set contains any code required by the project which is not in the standard image. - Publish the project. - You will be asked if you want to include the changes in the change set. Answer 'Yes'

Classes and projects

I made a tiny class and saved it as a project to Bobs Super Swiki. That worked ok but when I try to load it it asks me what modern class the class I createt should translate to. How do I make projects with includes class changes etc ? Karl

I get reminded occasionally when I use a gradient that doesn't look so nice for folks in 8-bit mode. It's tough to know what percentage of present/potential users have slow/low/small machines. I agree that any expensive look should be easily turned off by those who can't afford it. Cheers, Bob P.S. If you'd like me to look at redraw in the blue look, point me to the current change set.

The translucent portions of windows may be causing this redraw, although it's not quite obvious that the features cause this particular redraw behavior. This is something I've thought of before that we should beware of if we change the default look: snazzier graphics will be expensive on slower machines. The least we'd need is a page of preferences for switching the various expensive features on and off. Henrik
