class UIng::Table

• UIng::Table
• UIng::Control
• Reference
• Object

Overview

Table::Model manages data for Table controls.

CRITICAL MEMORY MANAGEMENT WARNINGS:

1. Table::Model MUST be freed AFTER all Tables using it are destroyed
2. Table::Model::Handler callbacks become invalid after Table::Model is freed
3. DO NOT rely on GC/finalize for automatic cleanup - use explicit free()
4. Avoid circular references in Table::Model::Handler callbacks

Safe usage pattern: model_handler = Table::Model::Handler.new model = Table::Model.new(model_handler) table = Table.new(model)

... use table ...

table.destroy # Destroy table first model.free # Then free model

Instance Method Summary

• #append_button_column(name : String, button_model_column : Int32, clickable : Int32 | ModelColumn) : Nil

  clickable follows the same rules as column editability.

• #append_checkbox_column(name : String, checkbox_model_column : Int32, editable : Int32 | ModelColumn) : Nil
• #append_checkbox_text_column(name : String, checkbox_model_column : Int32, checkbox_editable : Int32 | ModelColumn, text_model_column : Int32, text_editable : Int32 | ModelColumn, table_text_column_optional_params : TextColumnOptionalParams) : Nil
• #append_checkbox_text_column(name : String, checkbox_model_column : Int32, checkbox_editable : Int32 | ModelColumn, text_model_column : Int32, text_editable : Int32 | ModelColumn, color_model_column : Int32) : Nil
• #append_checkbox_text_column(name : String, checkbox_model_column : Int32, checkbox_editable : Int32 | ModelColumn, text_model_column : Int32, text_editable : Int32 | ModelColumn) : Nil
• #append_image_column(name : String, image_model_column : Int32) : Nil
• #append_image_text_column(name : String, image_model_column : Int32, text_model_column : Int32, editable : Int32 | ModelColumn, table_text_column_optional_params : TextColumnOptionalParams) : Nil
• #append_image_text_column(name : String, image_model_column : Int32, text_model_column : Int32, editable : Int32 | ModelColumn, color_model_column : Int32) : Nil
• #append_image_text_column(name : String, image_model_column : Int32, text_model_column : Int32, editable : Int32 | ModelColumn) : Nil
• #append_progress_bar_column(name : String, progress_model_column : Int32) : Nil
• #append_text_column(name : String, text_model_column : Int32, editable : Int32 | ModelColumn, table_text_column_optional_params : TextColumnOptionalParams) : Nil
• #append_text_column(name : String, text_model_column : Int32, editable : Int32 | ModelColumn, color_model_column : Int32) : Nil
• #append_text_column(name : String, text_model_column : Int32, editable : Int32 | ModelColumn) : Nil

  editable can be :never, :always, or a model column whose values control editability for each row.

• #clear_on_header_clicked : Nil

  Clears the callback; equivalent to #on_header_clicked(nil).

• #clear_on_row_clicked : Nil

  Clears the callback; equivalent to #on_row_clicked(nil).

• #clear_on_row_double_clicked : Nil

  Clears the callback; equivalent to #on_row_double_clicked(nil).

• #clear_on_selection_changed : Nil

  Clears the callback; equivalent to #on_selection_changed(nil).

• #column_set_width(column : Int32, width : Int32) : Nil
• #column_width(column : Int32) : Int32
• #each_selected_index(&block : Int32 -> _) : Nil

  Yields each selected row index without copying the native row array into a Crystal Array.
