Re: [Pharo-users] GLM: preserving columns width in tables // getting the actual column
Hi Tudor, all
thanks for your reply.
I would like your opinion about the cleanest way to add this considering
that:
- Columns are added in GLMMorphicListingRenderer>> treeMorphFor:
tmpTreeModel and: aPresentation
- GLMMorphTreeColumn implements currentWidth: and currentWidth
Should I setup an observer so that when the GLMMorphTreeColumn has its
width changed the presentation is notified? then expose in
GLMTablePresentation the actual widths of the columns?
That would do the trick for me, but not sure about the proper way to add
this behavior
Thanks!
Arturo

Re: [Pharo-users] GLM: preserving columns width in tables // getting the actual column
Hi,
There is no built-in support for something like this.
You would have to change the internal logic of the TablePresentation renderer.

[Pharo-users] GLM: preserving columns width in tables // getting the actual column
Hi All,
I would like to preserve the width of columns for tables after a user has
changed them (not fast tables, but it should be similar).
To do this I plan to get the actual width of the columns and use it the
next time I need to create the table.
Please consider the following snippet:
browser := GLMTabulator new.
browser row: #Example.
browser transmit
to: #Example;
andShow: [ :a |
*table*:= a table.
table
column: 'Class Name' evaluated:[:clazz| clazz name] width:100;
column: '# of methods' evaluated:[:clazz| clazz methods size] width:150;
children:[:clazz| clazz subclasses];
shouldRootsExpand: true ].
browser openOn: {Object}.
If I resize the columns in the UI and then run
*table* columns collect:[:c| c width]
I get the original sizes but not the actual ones.
I have two questions:
1- Is there a way to get the actual values for column width?
2 - Is there an event that gets fired when column sizes are changed in
the UI?
If there is such an event maybe all that is needed it to update the width
inst. var in the columns (GLMTableColumns).
TIA
Arturo
