Mass api change from GtkExtendedLayout --> GtkSizeRequest This commit makes a few massive changes to the extended layout code: a.) gtkextendedlayout.c --> gtksizerequest.c b.) _is_height_for_width --> get_request_mode() c.) get_desired_size(), get_desired_width(), get_desired_height() --> get_size(), get_width(), get_height() This is the first partial commit and only effects portions of the tree that have already been merged in master (in order to easily cherry pick this commit).

Reduce memory consumption of the size request cache. This patch makes contextual height-for-width request caching optional (the contextual cache is not allocated for widgets that report GTK_SIZE_REQUEST_CONSTANT_SIZE).

Cache heights-for-range-of-widths instead of height for every width. This patch optimizes window resizes by assuming that if a widget has the same height at a width of 50 as with a width of 150, the height for width 100 will also be the same. The patch also further optimizes the cache allocator, now there are 2 pointer arrays of up to a maximum of 5 requests, the arrays will only be allocated if a request is ever made in that orientation and the array will be sparse until each request is made (i.e. if a label can only wrap to 3 lines, there will only be 3 out of a possible 5 SizeRequest structures allocated to cache it).

Cache heights-for-range-of-widths instead of height for every width. This patch optimizes window resizes by assuming that if a widget has the same height at a width of 50 as with a width of 150, the height for width 100 will also be the same. The patch also further optimizes the cache allocator, now there are 2 pointer arrays of up to a maximum of 5 requests, the arrays will only be allocated if a request is ever made in that orientation and the array will be sparse until each request is made (i.e. if a label can only wrap to 3 lines, there will only be 3 out of a possible 5 SizeRequest structures allocated to cache it).

Added gtk_extended_layout_is_height_for_width() Added an indicator telling whether a widget prefers to be allocated as height-for-width or width-for-height. Usually this depends on the orientation of a container or the nature of a content widget like GtkLabel. This indicator is only used in the seldom case where a parent is allocating free space to the child and the child can flow in either direction, GtkWindow and GtkScrolledWindow are users of this api.

Cache heights-for-range-of-widths instead of height for every width. This patch optimizes window resizes by assuming that if a widget has the same height at a width of 50 as with a width of 150, the height for width 100 will also be the same. The patch also further optimizes the cache allocator, now there are 2 pointer arrays of up to a maximum of 5 requests, the arrays will only be allocated if a request is ever made in that orientation and the array will be sparse until each request is made (i.e. if a label can only wrap to 3 lines, there will only be 3 out of a possible 5 SizeRequest structures allocated to cache it).

widget: Emit initial style-set signal in the same situations as GTK2 This ensures that widgets that aren't ported and rely on the style-set signal being emitted work as well as before. They should not rely on style-set being emitted however. Note that this function is a no-op if the initial style has been set already and is very cheap if it has not been set yet. It only becomes relevant if the resulting style actually gets used. https://bugzilla.gnome.org/show_bug.cgi?id=639584

Fixing documentation of gtk_widget_get_request_mode()
2010-09-27 06:11:27 +00:00
* gtk_widget_get_request_mode:
Move GtkSizeRequest into GtkWidget It doesn't make sense to keep them separate as GtkSizeRequest requires a GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have one without the other. It also makes the code a lot easier because no casts are required when calling functions. Also, the names would translate to gtk_widget_get_width() and people agreed that this would be a too generic name, so a "preferred" was added to the names. So this patch moves the functions: gtk_size_request_get_request_mode() => gtk_widget_get_request_mode() gtk_size_request_get_width() => gtk_widget_get_preferred_width() gtk_size_request_get_height() => gtk_widget_get_preferred_height() gtk_size_request_get_size() => gtk_widget_get_preferred_size() gtk_size_request_get_width_for_height() => gtk_widget_get_preferred_width_for_height() gtk_size_request_get_height_for_width() => gtk_widget_get_preferred_height_for_width() ... and moves the corresponding vfuncs to the GtkWidgetClass. The patch also renames the implementations of the vfuncs in widgets to include the word "preferrred".

Move GtkSizeRequest into GtkWidget It doesn't make sense to keep them separate as GtkSizeRequest requires a GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have one without the other. It also makes the code a lot easier because no casts are required when calling functions. Also, the names would translate to gtk_widget_get_width() and people agreed that this would be a too generic name, so a "preferred" was added to the names. So this patch moves the functions: gtk_size_request_get_request_mode() => gtk_widget_get_request_mode() gtk_size_request_get_width() => gtk_widget_get_preferred_width() gtk_size_request_get_height() => gtk_widget_get_preferred_height() gtk_size_request_get_size() => gtk_widget_get_preferred_size() gtk_size_request_get_width_for_height() => gtk_widget_get_preferred_width_for_height() gtk_size_request_get_height_for_width() => gtk_widget_get_preferred_height_for_width() ... and moves the corresponding vfuncs to the GtkWidgetClass. The patch also renames the implementations of the vfuncs in widgets to include the word "preferrred".

Added gtk_extended_layout_is_height_for_width() Added an indicator telling whether a widget prefers to be allocated as height-for-width or width-for-height. Usually this depends on the orientation of a container or the nature of a content widget like GtkLabel. This indicator is only used in the seldom case where a parent is allocating free space to the child and the child can flow in either direction, GtkWindow and GtkScrolledWindow are users of this api.

Move GtkSizeRequest into GtkWidget It doesn't make sense to keep them separate as GtkSizeRequest requires a GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have one without the other. It also makes the code a lot easier because no casts are required when calling functions. Also, the names would translate to gtk_widget_get_width() and people agreed that this would be a too generic name, so a "preferred" was added to the names. So this patch moves the functions: gtk_size_request_get_request_mode() => gtk_widget_get_request_mode() gtk_size_request_get_width() => gtk_widget_get_preferred_width() gtk_size_request_get_height() => gtk_widget_get_preferred_height() gtk_size_request_get_size() => gtk_widget_get_preferred_size() gtk_size_request_get_width_for_height() => gtk_widget_get_preferred_width_for_height() gtk_size_request_get_height_for_width() => gtk_widget_get_preferred_height_for_width() ... and moves the corresponding vfuncs to the GtkWidgetClass. The patch also renames the implementations of the vfuncs in widgets to include the word "preferrred".
