If the cursor is inside the subcell, call the show_tooltip on it.

2000-09-15  Iain Holmes  <iain@helixcode.com>

	* 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  <iain@helixcode.com>

	* 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  <iain@helixcode.com>

	* 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  <iain@helixcode.com>

	* 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.
