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

Hi,

There is no built-in support for something like this.

You would have to change the internal logic of the TablePresentation renderer.

Cheers,

Re: 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
