Hello Robert,
I asked David Röthlisberger and he did it in same way you wrote.
Best regards, Juraj

Hi Juraj,
I remember you wrote about changes which gives icons to column items. Is it also possible to set a color in your implementation? I may help you to finish, because I need to extend visualization support (for example green Trait names) in OB.
Yes, it is possible to set colors for the items. I use a subclass of LazyListMorph and override #colorForRow: to answer the color of the column item. And then i also introduced a new OBPluggableListMorph class and let it answer the new OBLazyListMorph class in #listMorphClass, as Robert Krahn explained.
OBLazyListMorph >> #colorForRow: reads like this:
colorForRow: row | item | ^(selectedRow notNil and: [ row = selectedRow]) ifTrue: [ Color red ] ifFalse: [ item := self getListItem: row. item isText ifTrue: [item colorAt: 1] ifFalse: [self color] ].
Now you can use the TextColor>>green attribute when building the strings for the column items.
This seems to be the easiest solution. With these two new classes I could also add support for icons.
Cheers, David

Sorry, I don't want to spam you but I thought about a possible solution for that issue.
The first thing one could do is to subclass LazyListMorph to have a Morph which permits the displayStrings to keep their color.
Then there
is the need for a new PluggableListMorph which overrides PluggableListMorph >>listMorphClass to get this subclass of LazyListMorph. The next thing is to construct another
OBMorphBuilder
which changes #listMorphForColumn:.
Then a new builder exists which delivers browsers with the wanted property. I don't know if there are other classes which have to be changed (OBPane?) or if there is an easier solution. Please give me your opinion.
Robert

Yes, thats why the standard colors in LazyListMorph overwrite your chosen color. LazyListMorph >>display: atRow:on: looks like that:
display: item atRow: row on: canvas "display the given item at row row" | drawBounds | drawBounds := self drawBoundsForRow: row. drawBounds := drawBounds intersect: self bounds. item isText ifTrue: [ canvas drawString: item in:
drawBounds font: (font
emphasized: (item emphasisAt: 1)) color: (self colorForRow: row) ] ifFalse: [ canvas drawString: item in:
drawBounds font: font
color: (self colorForRow: row) ].
The item is your displayString but the color is changed to LazyListMorph >>colorForRow: which turns out to be the follow:
colorForRow: row ^(selectedRow notNil and: [ row = selectedRow]) ifTrue: [ Color red ] ifFalse: [ self color ].
It seems that those things are really in the guts of the
system and
because of that they cannot be parameterized easily (yet). _______________________________________________ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners
