Re-enable the "find" dialog

2000-10-23  Havoc Pennington  <hp@redhat.com>

        * gtk/testtext.c: Re-enable the "find" dialog

	* gtk/testgtk.c: Add test for gdk_drawable_get_image

	* gdk/gdkwindow.c (gdk_window_begin_paint_region): Fix bug where
	the arguments to gdk_draw_drawable were in the wrong order
	(gdk_window_paint_init_bg): This function was ignoring the
	init_region, instead of clipping to it, so the entire backing
	pixmap was cleared on every begin_paint()
	(gdk_window_begin_paint_region): Hmm, the same list-walking bug
	was in here again, the loop kept using the same GtkWindowPaint
	over and over.
	(gdk_window_begin_paint_region): Fix a bug where we had two
	x_offset instead of x_offset and y_offset

	* gdk/gdkdraw.c (gdk_drawable_get_image): get composite drawable
	before we get the image.
	(gdk_draw_drawable): get the composite before we draw the drawable.
	(gdk_drawable_real_get_composite_drawable): default
	get_composite_drawable implementation that returns the drawable
	itself

	* gdk/gdkdrawable.h (struct _GdkDrawableClass ): Add
	get_composite_drawable virtual function

	* gdk/gdkwindow.c (gdk_window_begin_paint_region): Fix a cheesy
	list-walking bug

	* gdk/x11/gdkdrawable-x11.c (gdk_x11_draw_drawable): Add a hack to
	make this work if the source drawable is a GdkDrawableImplX11
	instead of a public drawable type. This is really broken; the
	problem is that GdkDrawable needs a virtual method get_xid(), but
	of course that doesn't work in practice. Enter RTTI.

	Also, improve mismatched depth message.

	* gdk/gdkpixmap.c (gdk_pixmap_get_image): Implement get_image for
	GdkPixmap

	* gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_class_init):
	install _gdk_x11_get_image as our implementation of get_image

	* gdk/x11/gdkimage-x11.c (gdk_image_get): Rename to
	_gdk_x11_get_image and export for use in gdkdrawable-x11.c

	* gdk/gdkimage.c (gdk_image_get): Make this just a wrapper around
	gdk_drawable_get_image

	* gdk/gdkdraw.c (gdk_drawable_get_image): call virtual get_image

	* gdk/gdkdrawable.h (struct _GdkDrawableClass ): Virtualize
	get_image

	* gtk/gtktreestore.c (gtk_tree_store_get_node): remove weird
	trailing semicolon after for loop

aren't familiar with the widgets. Removed objects_grouped.sgml

<title>Conceptual Overview</title>
<para>
GTK+ has an extremely powerful framework for multiline text editing. The
primary objects involved in the process are <link
linkend="GtkTextBuffer">GtkTextBuffer</link>, which represents the text being
edited, and <link linkend="GtkTextView">GtkTextView</link>, a widget which can
display a <link linkend="GtkTextBuffer">GtkTextBuffer</link>. Each buffer can be
displayed by any number of views.
</para>
<para>
Text in a buffer can be marked with <firstterm>tags</firstterm>. A tag is an
attribute that can be applied to some range of text. For example, a tag might be
called "bold" and make the text inside the tag bold. However, the tag concept is
more general than that; tags don't have to affect appearance. They can instead
affect change the behavior of mouse and key presses, "lock" a range of text so
the user can't edit it, or countless other things. A tag is represented by a
<link linkend="GtkTextTag">GtkTextTag</link> object. One <link
linkend="GtkTextTag">GtkTextTag</link> can be applied to any number of text
ranges in any number of buffers.
</para>
<para>
Each tag is stored in a <link
linkend="GtkTextTagTable">GtkTextTagTable</link>. A tag table defines a set of
tags that can be used together. Each buffer has one tag table associated with
it; only tags from that tag table can be used with the buffer. A single tag
table can be shared between multiple buffers, however.
</para>
<para>
Tags can have names, which is convenient sometimes (for example, you can name
your tag that makes things bold "bold"), but they can also be anonymous (which
is convenient if you're creating tags on-the-fly).
</para>
<para>
Most text manipulation is accomplished with <firstterm>iterators</firstterm>,
represented by a <link linkend="GtkTextIter">GtkTextIter</link>. An iterator
represents a position in the text buffer. <link
linkend="GtkTextIter">GtkTextIter</link> is a struct designed to be allocated on
the stack; it's guaranteed to be copiable by value and never contain any
heap-allocated data. Iterators are not valid indefinitely; whenever the buffer
is modified in a way that affects the number of characters in the buffer, all
outstanding iterators become invalid. (Note that deleting 5 characters and then
reinserting 5 still invalidates iterators, though you end up with the same
number of characters).
</para>
<para>
Because of this, iterators can't be used to preserve positions across buffer
modifications. To preserve a position, the <link
linkend="GtkTextMark">GtkTextMark</link> object is ideal. You can think of a
mark as an invisible cursor or insertion point; it floats in the buffer, saving
a position. If the text surrounding the mark is deleted, the mark remains in the
position the text once occupied; if text is inserted at the mark, the mark ends
up either to the left or to the right of the new text, depending on its
<firstterm>gravity</firstterm>. The standard text cursor in left-to-right
languages is a mark with right gravity, because it stays to the right of
inserted text.
</para>
<para>
Like tags, marks can be either named or anonymous. There are two marks built-in
to <link linkend="GtkTextBuffer">GtkTextBuffer</link>; these are named
<literal>"insert"</literal> and <literal>"selection_bound"</literal> and refer
to the insertion point and the boundary of the selection which is not the
insertion point, respectively. If no text is selected, these two marks will be
in the same position. You can manipulate what is selected and where the cursor
appears by moving these marks around.
<footnote>
<para>
If you want to place the cursor in response to a user action, be sure to use
gtk_text_buffer_place_cursor(), which moves both at once without causing a
temporary selection (moving one then the other temporarily selects the range in
between the old and new positions).
</para>
</footnote>
</para>
</refsect1>
<refsect1>
<title>Simple Example</title>
<para>
The simplest usage of <link linkend="GtkTextView">GtkTextView</link>
might look like this:
<programlisting>
/* Get a buffer (it's a GObject, not a GtkObject, so we own a reference
* after this). Passing NULL as argument causes an empty tag table to be
* automatically created.
*/
buffer = gtk_text_buffer_new (NULL);
view = gtk_text_view_new_with_buffer (buffer);
/* view holds a reference now */
g_object_unref (G_OBJECT (buffer));
/* Now you might put the view in a container and display it on the
* screen; when the user edits the text, signals on the buffer
* will be emitted, such as "changed", "insert_text", and so on.
*/
</programlisting>
</para>

</para>
<para>
A #GtkTextMark is like a bookmark in a text buffer; it preserves a position in
the text. You can convert the mark to an iterator using
gtk_text_buffer_get_iter_at_mark(). Unlike iterators, marks remain valid across
buffer mutations, because their behavior is defined when text is inserted or
deleted. When text containing a mark is deleted, the mark remains in the
position originally occupied by the deleted text. When text is inserted at a
mark, a mark with <firstterm>left gravity</firstterm> will be moved to the
beginning of the newly-inserted text, and a mark with <firstterm>right
gravity</firstterm> will be moved to the end.
<footnote>
<para>
"left" and "right" here refer to logical direction (left is the toward the start
of the buffer); in some languages such as Hebrew the logically-leftmost text is
not actually on the left when displayed.
</para>
</footnote>
</para>
<para>
Marks are reference counted, but the reference count only controls the validity
of the memory; marks can be deleted from the buffer at any time with
gtk_text_buffer_delete_mark(). Once deleted from the buffer, a mark is
essentially useless.
</para>
<para>
Marks optionally have names; these can be convenient to avoid passing the
#GtkTextMark object around.
</para>
<para>
Marks are typically created using the gtk_text_buffer_create_mark() function.
