2003-10-14 Suresh Chandrasekharan <suresh.chandrasekharan@sun.com> * Support for preedit in e-text widgets. * gal/gal/e-text/e-text.c: Added e_text_preedit_changed_cb and insert_preedit_text. * Modified the following functions. (e_text_draw) Calls insert_preedit_text also cursor pos @ the end of text->selection_start + text->preedit_len (e_text_event) Added hooks for preedit_cb (e_text_init) Inits text->preedit_len (e_text_retrieve_surrounding_cb) Removed printf (e_text_delete_surrounding_cb) Correct params for gtk_editable_delete_text to make it work. * gal/gal/e-text/e-text.h: Added preedit_len in struct _EText 2003-09-25 Suresh Chandrasekharan <suresh.chandrasekharan@sun.com> * Fix for "44222 task summary entry widget not i18ned". The following files are changed. * gal/gal/e-table/e-cell-text.c: Lots of changes for i18n selection/input support. Added these functions for input method support. (e_cell_text_preedit_changed_cb) (e_cell_text_commit_cb) (e_cell_text_retrieve_surrounding_cb) (e_cell_text_delete_surrounding_cb) (layout_with_preedit) This function inserts the preedit string with the right attribs to the layout text. (build_attr_list) Creates the PangoAttrList with bold/stikeout/underline as applicable for the current ECellText. The following functions are modified. (ect_stop_editing): disconnect signal handlers when editing stops (ect_draw): Changes for including the preedit only to the currently selected row/col. Also display the cursor at the end of preedit text. (ect_event): Connects the IM callbacks to the key press event. Disconnect when not in editing mode. Also a special flag to see when Enter key pressed in preedit mode, the text is committed only not a new row is created. This woks in conjunction with the changes made in the eti_event in e-table-item.c file and e-cell.h. (ect_height): Changes due to parameters changing for generate_layout (ect_enter_edit): Initialization of im_context for a cell text and assoociated flags. (ect_max_width): Changes due to parameters changing for generate_layout. (ect_max_width_by_row): Changes due to parameters changing for generate_layout. (ect_show_tooltip): Changes due to parameters changing for generate_layout. (e_cell_text_construct): check whether paramters are NULL. (get_position_from_xy): Changes due to parameters changing for generate_layout. (_insert): Set the selection_start as the minimum of strlen(edit->text) and selection_start. Used to correct the preedit_string length which may have added to the selection_start. (e_cell_text_view_command): When inserting, if in the preedit mode do not delete the selection. (_selection_get): Set utf8 data instead of string data. (_selection_received): Take in UTF8_ATOM inaddition to GDK_SELECTION_TYPE_STRING. (e_cell_text_view_get_selection): Make utf8 data when acting as a selection source. * gal/e-table/e-cell-text.h : Included <gtk/gtkmenu.h> * gal/e-table/e-cell.h: Added enum E_CELL_PREEDIT to ECellFlags * gal/e-table/e-table-item.c: (eti_event) Changes for not committing the edited text as a seperate row in preedit mode. * gal/e-table/e-table.c: (table_canvas_focus_event_cb) To have proper im_context focus for the ecanvas holding the e-table. svn path=/trunk/; revision=22882
