configure.in acheader.h gdk/gdkwindow.c Check for Shape extension both on Sun May 3 13:38:22 1998 Owen Taylor <otaylor@gtk.org> * configure.in acheader.h gdk/gdkwindow.c Check for Shape extension both on the client and server side. (And, more importantly, check for the shape extension so we may include -lXext even when compiling with --disable-xshm) Don't set override_redirect on all shaped windows. It isn't necessary. * gdk/gdkwindow.c: Set ->colormap to NULL for root and foreign windows. Use this to check if we need to get the colormap from X. Fri May 1 22:32:47 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkbutton.c (gtk_button_paint): Draw the areas between the default and the button always in GTK_STATE_NORMAL. * gtk/gtkrange.c (gtk_range_style_set): Added a style_set callback. Fri May 1 16:40:57 1998 Owen Taylor <otaylor@gtk.org> * gdk/gdkpixmap.c (gdk_pixmap_colormap_create_from_xpmp[_d]): Fix a buffer overflow on pixmaps that claim to have more than 31 characters per pixel. (gdk_pixmap_read_string): Don't wrap around strings longer than half of address space ;-) * gtk/gtk[vh]ruler.c gtk/gtkinputdialog.c: Expand some buffers that were used for printing integers. * */* (almost): Style: All int foo () { ... } changed to int foo (void) { ... } ^^^^^^^ This is why some many files changed Even where there were proper prototypes elsewhere. * gdk/gxid.c (handle_claim_device): Some extra checks. It isn't safe against being fed bad X id's, but at least it should be safe against deleting all your files.

Added gdk_text/string_extents() - too calculate all the metrics at once of Tue Jul 21 12:42:01 1998 Owen Taylor <otaylor@redhat.com> * gdk/gdk.h gdk/gdkfont.c: Added gdk_text/string_extents() - too calculate all the metrics at once of a string, including things which weren't calculated before. * gtk/Makefile.am gtk/gtk.h gtk/gtktearoffmenu.[ch]: New MenuItem type, that when put as the first thing in a menu, makes the menu tearoff. Currently drawn as a dashed line. * gtk/gtkmenuitem.h gtk/gtkcheckmenuitem.c: Added a flag "hide_on_activate" to the MenuItem class structure to allow check and radio buttons to be changed with <Space> without hiding the menu. * gtk/gtkaccellabel.[ch]: Added new capabilities to set a underline_group and underline_mods for the label - accelerators added in the underline group matching underline_mods will be displayed as an underline character. This doesn't work - Save As needs to be underlined as Save _As. * gtk/gtkitemfactory.c: - Create a AccelGroup for each MenuShell we create. - If an '&' appears before a character 'c' in the path, then make 'c' an accelerator in the menu's accel group, and if the menuitem is menubar <alt>C an accelerator in the itemfactory's accel group. * gtk/gtklabel.[ch]: Add support for a pattern arg - which is a string. If an '_' appears in this string, the corresponding position in the label is underlined. Add gtk_label_parse_uline() convenience function which takes a string with embedded underlines, sets the pattern and label, and returns the accelerator keyval. * gtk/gtkmenu.[ch]: Make menus no longer a toplevel widget. Instead, they create a GtkWindow and add themselves to that. (When torn off, another new feature, they create another GtkWindow to hold the torn off menu) New function gtk_menu_set_tearoff_state() * gtk/gtkenums.h gtk/gtkmenushell.[ch] gtk/gtkenums.h: Added action signals for keyboard navigation of menus. * gtk/gtkmenushell.c: Key press handler which activates bindings for navigation, and accelerators, for handling underline accelerators. Exported functions to select and activate menu items in a menushell. * gtk/testgtk.c: Added a new "Item Factory" test which tests GtkItemFactory and the new keyboard navigation of menus.
