Dynamic creation of a tabbed book of tables

[Eric Hutton]

Hi all,

So I'm trying to create a bunch of tabbed tables in a tabbook, but I don't know in advance how many I will need, the number will depend on some data being read in by the system.

doing this:

        years_on_file.each do |year|
            @customs_summary_year_tab = FXTabItem.new(@customs_summary_tabbook, " #{year} ",
                :opts => TAB_TOP_NORMAL)
            @customs_summary_year_frame = FXHorizontalFrame.new(@customs_summary_tabbook,
                :opts => FRAME_THICK|FRAME_RAISED|FRAME_LINE)
            @customs_summary_table = FXTable.new(@customs_summary_year_frame,
                :opts => TABLE_COL_SIZABLE|TABLE_ROW_SIZABLE|LAYOUT_FILL|TABLE_READONLY)
            @customs_summary_table.setTableSize(num_of_rows, num_of_cols)
            @customs_summary_table.rowHeaderWidth = $row_col_frame_size
            @customs_summary_table.columnHeaderHeight = $row_col_frame_size

            ... more code that goes on to fill data into each table...

        end

will generate a number of tabs, but, of course, they all get filled with the identical data (that generated by the last iteration through the block).  I'm thinking that myabe I need to somehow use some sort of dyanmic naming scheme for my tabs and tables, but I'm at a loss as to how to do that.

Any suggestions?

Thanks!

Hmm, no, got that wrong, so this will create each of the tabbed tables, but the problem is that the instance variable names will be only associated with the last objects created, so there is no way to reference and update values in the earlier tables (without removing and recreating them of course).

I guess what I need is to be able to use some sort of hash of the object ids for the individual tabs and tables created? ummm maybe using something like eachChildRecursive to nab the object ids?

Maybe just use instance_variable_set/instance_variable_get to set/get variables?

Sorry for the delayed response, but I've been on vacation.

Technically, you can always "get to" these widgets by navigating  
through the widget hierarchy using methods like FXWindow#each_child,  
but that can be a little tricky. Why don't you just store them in  
arrays or hashes, e.g.

        customs_summary_year_tabs = []
        customs_summary_tables = []
        years_on_file.each do |year|
                customs_summary_year_tabs << FXTabItem.new(...)
                ...
                customs_summary_year_tables << FXTable.new(...)
        end

Hope this helps,

Lyle

No need to apologize!  No one expects you to be on call to answer questions 24/7, or even at all if you don't want to!

Putting them in a hash was exactly what I had in mind, but it didn't seem to be working for me so I wasn't sure if it was possible.  I'll have to experiment with that a bit more. As a workaround I've been doing the thing you dislike - removing  (using each_child, remove_child) and recreating, rather than redrawing.
