Setting rowHeight: for Spec FastTableModel

Hi,

I have a code like this:

FastTableModel new

displayBlock: [ :node | node name ];

items: Collection withAllSubclasses;

openWithSpec.

Which works fine. But I would like to define row height for each item. FTTableMorph has a method rowHeight:.

Is it possible?

One possible use case could be:

FastTableModel new

displayBlock: [ :node | node name,

String cr, ‘ number of methods: ', node methods size asString ];

items: Collection withAllSubclasses;

"rowHeight: 50;” “does not work"

openWithSpec

In that case, each list item is composed by a class name on the first line, and the number of methods on the second line.

For FTTableMorph the code looks like this:

FTTableMorph new

extent: 650@500;

selectRowIndex: 1;

showFirstRowSelection;

dataSource: (FTEasyListDataSource new

elements: Collection withAllSubclasses;

display: [ :node |

Smalltalk ui theme newColumnIn: World for: {

node name asStringMorph.

(' number of methods: ', node methods size asString)

asStringMorph }]);

rowHeight: 50;

beMultipleSelection;

openInWindow

Or do you propose another solution?

Thanks!

Juraj

Sure. Not all properties of fasttable are exposed, and I never got a
good answer on the design question of what and how to expose and
propagate properties in Spec. I see the following design questions:

Exposing all the Morphic properties makes for a stronger dependency on
Morphic. Spec itself is written so it can be easily ported from one
underlying widget & gui layer to another (bloc, cocoa, qt, less so for
web?), and different layers have different properties. What is common
and what needs adapters or even layer-specific code?

When nesting components, how do properties propagate? Define once and
reuse everywhere is the goal, but that requires defining where
components can find property values: Theme, Application, Session. In
Spec there is no model/API defined for that, and there is no systematic
approach taken, just pragmatic choices.

What considerations are there to have individual row heights?

i.e. How close are we to having a spreadsheet interface like simplfied Excel?

The way I understand FastTable, it is not possible to have each item with different height.

that’s correct.

There was a proposal to give it variable heights but I think it was never implemented.
