Move all X specific code into the x11/ directory. Aside from shuffling Mon Nov 8 14:47:04 1999 Owen Taylor <otaylor@redhat.com> Move all X specific code into the x11/ directory. Aside from shuffling things around, did the following: * gdk/gdkprivate.h gdk/gdk.h gdk/x11/gdkmain-x11.h: Add gdk_arg_context_* - a simple argument parsing system in the style of popt. * gdk/gdkdrawable.[ch] gdk/gdkprivate.h gdk/gdkwindow.[ch] gdk/x11/gdkprivate-x11.h: Remove X specific stuff from GdkDrawable and GdkWindowPrivate - add ->klass and ->klass_data fields. The klass_data field points to an auxilliary structure that is windowing system dependent. * gdk/gdkfont.c: Make most of the measurement functions simply wrappers around gdk_text_extents(). * gdk/gdkfont.c gdk/gdkprivate.h gdk/x11/gdkfont-x11.c: Add a _gdk_font_strlen() function that hides the weird behavior in gtk+-1.[02] where a string is interpreted differently for 8-bit and 16-bit fonts. * gdk/gdkevents.c: Add a new function gdk_event_button_generate() to store common code for synthesizing double/triple press events. * gdk/gdkgc.[ch]: Virtualize in the same way as gdkdrawable.h. Make all the function that modify an existing GC simply wrappers around gdk_gc_set_values(). * gdk/gdkcc.[ch]: Moved into x11/ directory in preparation for throwing out later. * gdk/gdkfont.c gdk/gdkimage.c gdk/gdkcolor.c: Change GdkFontPrivate, GdkImagePrivate and GdkColormapPrivate to have a windowing system dependent part (GdkFontPrivateX etc.) that "derives" from the system-independent part. * configure.in gdk/x11/Makefile.in gdk/x11/gdkinput*.c: Got rid of the included-source-files for XInput in favor of automake conditionals. (Which didn't exist when XInput support was originally added.) * gdk/gdkrgb.c: Remove the visual id from the debugging statements since that is X11 specific; print out type/depth info instead.

gdk/surface: Replace move_to_rect() with GdkPopupLayout based API Replace the gdk_surface_move_to_rect() API with a new GdkSurface method called gdk_surface_present_popup() taking a new GdkPopupLayout object describing how they should be laid out on screen. The layout properties provided are the same as the ones used with gdk_surface_move_to_rect(), except they are now set up using GdkPopupLayout. Calling gdk_surface_present_popup() will either show the popup at the position described using the popup layout object and a new unconstrained size, or reposition it accordingly. In some situations, such as when a popup is set to autohide, presenting may immediately fail, in case the grab was not granted by the display server. After a successful present, the result of the layout can be queried using the following methods: * gdk_surface_get_position() - to get the position relative to its parent * gdk_surface_get_width() - to get the current width * gdk_surface_get_height() - to get the current height * gdk_surface_get_rect_anchor() - to get the anchor point on the anchor rectangle the popup was effectively positioned against given constraints defined by the environment and the layout rules provided via GdkPopupLayout. * gdk_surface_get_surface_anchor() - the same as the one above but for the surface anchor. A new signal replaces the old "moved-to-rect" one - "popup-layout-changed". However, it is only intended to be emitted when the layout changes implicitly by the windowing system, for example if the monitor resolution changed, or the parent window moved.

gdk: Add support for OpenGL This adds the new type GdkGLContext that wraps an OpenGL context for a particular native window. It also adds support for the gdk paint machinery to use OpenGL to draw everything. As soon as anyone creates a GL context for a native window we create a "paint context" for that GdkWindow and switch to using GL for painting it. This commit contains only an implementation for X11 (using GLX). The way painting works is that all client gl contexts draw into offscreen buffers rather than directly to the back buffer, and the way something gets onto the window is by using gdk_cairo_draw_from_gl() to draw part of that buffer onto the draw cairo context. As a fallback (if we're doing redirected drawing or some effect like a cairo_push_group()) we read back the gl buffer into memory and composite using cairo. This means that GL rendering works in all cases, including rendering to a PDF. However, this is not particularly fast. In the *typical* case, where we're drawing directly to the window in the regular paint loop we hit the fast path. The fast path uses opengl to draw the buffer to the window back buffer, either by blitting or texturing. Then we track the region that was drawn, and when the draw ends we paint the normal cairo surface to the window (using texture-from-pixmap in the X11 case, or texture from cairo image otherwise) in the regions where there is no gl painted. There are some complexities wrt layering of gl and cairo areas though: * We track via gdk_window_mark_paint_from_clip() whenever gtk is painting over a region we previously rendered with opengl (flushed_region). This area (needs_blend_region) is blended rather than copied at the end of the frame. * If we're drawing a gl texture with alpha we first copy the current cairo_surface inside the target region to the back buffer before we blend over it. These two operations allow us full stacking of transparent gl and cairo regions.
