icons in pluggablelistmorph

Hi,

I would like to specify an icon in a PluggableListMorph, but I cannot
find my way :). Can anyone tell me how to do it?

Cheers,
Doru

Re: icons in pluggablelistmorph

Maybe you can have a look at how OB does. By overriding the
OBNode>>icon, an icon appears on left to the item name.

Cheers,
Alexandre

You need to create a subclass of PluggableListMorph and LazyListMorph,
override #listMorphClass in the PluggableListMorph to return the lazy
morph class, and override the method #display:atRow:on: in the
LazyListMorph subclass to customize the low-level drawing of the list
item.

As you imagined all pretty simple and strait-forward, have a look at
the OB-Morphic for an example :-)

Cheers,
Lukas

do you also need to do what lukas suggested with the tree of alain?
Is there a reason not to use it?

Re: icons in pluggablelistmorph

Hi Stef,

The MorphTreeMorph widget of Alain follows a different design and
already provides a straightforward way to deal with icons.

I already use it for displaying trees in Glamour. But, that tree
widget appears to be significantly slower for displaying simple lists.
That is why I want to try with PluggableListMorph to see what can be
done and with what performance.

Cheers,
Doru

Re: icons in pluggablelistmorph

There's always Polymorph's PluggableIconListMorph...
Should do what you need.
