Thanks for trying BobsUI. There is no tutorial yet. I will make one and up=
load it to the swiki, but right now I am very busy and will not be able to =
work on BobsUI for a couple of months.
Until I write the tutorial, there are a few things you can look at if you w=
ant to experiment.
1. If you haven't done this, download BobsUI from SqueakMap.
2. The screenshot app is called ExampleRolodex. You can open this by typin=
g "ExampleRolodex open" in a workspace, highlighting it, and selecting "do =
it" from the workspace menu.
3. The ExampleRolodex is the most complete example I have of how most BobsU=
I windows will be written. It has an application model, (ExampleRolodex), =
composite models, and elements. You can start at ExampleRolodex and find h=
ow the models interact.
4. Developing visual components in BobsUI is unlike any other tool I have =
ever used, so it might be confusing for new BobsUI users. In order to deve=
lop a BobsUI window, you do not start with a window and add components to i=
t. You start with components, save them, and when they are done add them t=
o a window. The last thing you do is save the window. With models and vis=
ual components, you are always building from small to large in BobsUI.
5. The visual components in BobsUI are created from the bobsUI menu, which=
is found on the World menu. You create a component, like a button, and dro=
p it onto the desktop. Then you change the settings to what you want using=
the viewer button on its halo. When you are done, you push the bottom lef=
t purple button on its halo, and save it to a repository.=20
6. When visual components are saved, they are written in XML format to wha=
t I called a repository. You can browse the repositories with the reposito=
ry browser, which is located on the bobsUI menu. On the browser there are =
four panes from left to right. These panes are:
- Builders The builder that you will use to build components in th=
- Repositories Where components are written. There are two repositori=
es here, one for the view used by the bobsUI tools, and one for example win=
dows. You can also create your own. Whichever repository is set to defaul=
t is the one you will write components in.
- Categories The type of documents to make searching easier.
- Documents These are the names of the components. Selecting these =
will display their XML in the pane below.
For example, the XML document that represents the ExampleRolodex window is =
located in Examples, window, rolodexExampleView.
You can open any document in the repository for editing by selecting its na=
me and selecting "open" on the document name pane's menu.=20
There are other examples in the download. Mostly they are there for my tes=
ting purposes, but they are small enough that you can look at them and lear=
n something. They are much less complex than the ExampleRolodex. You can se=
nd "open" to any of these models in a workspace. These include:
I hope this gives you something to look at until I can write proper documen=
I have two warnings. One is the next update to BobsUI will likely break an=
y windows you create in the current version, so don't create anything impor=
tant, because you might have to delete it. I hope to release the next versi=
on in a few months. After that change, BobsUI will be more stable and safe=
to use. =20
The second warning is that the goal for BobsUI is to be able to write busin=
ess applications in it, but it is not close to that goal yet. If you look =
closely at the code you will find bugs, bad code, and things which are only=
beginning to be implemented that need a lot of work. Eventually these thi=
ngs will be worked on, but today it is only about half finished.
If you have any questions, you can send an email.
I'm starting with BobsUI, does exist in some place a Tutorial to make
things (as the screenshot app in the swiki page)?
