From 6e4ae07fbfce5845d48e8ba1992f64376a885ac4 Mon Sep 17 00:00:00 2001 From: Iain Holmes Date: Fri, 15 Sep 2000 21:42:38 +0000 Subject: If the cursor is inside the subcell, call the show_tooltip on it. 2000-09-15 Iain Holmes * e-cell-tree.c (ect_show_tooltip): If the cursor is inside the subcell, call the show_tooltip on it. * e-table-header-item.c (draw_button): Draw the arrow first, then take it's size into account when calculating how to draw the text. Use ellipsis if the text it too long. 2000-09-15 Iain Holmes * e-table-header-item.c (draw_button): Fix a crash by passing the canvas widget to gtk_paint_box. Reported by Radek. 2000-09-14 Iain Holmes * e-table-header-item.c (set_cursor): The column isn't resizable if it is the last, or if all other columns after it are not resizable. * e-cell-text.c (ect_max_width): Correctly calculate the width of the line of text. Unbuild the current cell and unref the lines as well. (build_current_cell): Initialize cell->style to 0; 2000-09-14 Iain Holmes * e-table-item.c: Start timers for the tooltip to appear, on motion events. * e-cell.[ch]: Add a new show_tooltip method. * e-cell-text.c (ect_show_tooltip): Show the tooltip. svn path=/trunk/;
