/**
* SECTION:gtkbutton
* @Short_description: A widget that emits a signal when clicked on
* @Title: GtkButton
*
* The #GtkButton widget is generally used to trigger a callback function that is
* called when the button is pressed. The various signals and how to use them
* are outlined below.
*
* The #GtkButton widget can hold any valid child widget. That is, it can hold
* almost any other standard #GtkWidget. The most commonly used child is the
* #GtkLabel.
*
* # CSS nodes
*
* GtkButton has a single CSS node with name button. The node will get the
* style classes .image-button or .text-button, if the content is just an
* image or label, respectively. It may also receive the .flat style class.
*
* Other style classes that are commonly used with GtkButton include
2016-03-03 00:10:59 +00:00
* .suggested-action and .destructive-action. In special cases, buttons
* can be made round by adding the .circular style class.
*
* Button-like widgets like #GtkToggleButton, #GtkMenuButton, #GtkVolumeButton,
* #GtkLockButton, #GtkColorButton, #GtkFontButton or #GtkFileChooserButton use
* style classes such as .toggle, .popup, .scale, .lock, .color, .file
* to differentiate themselves from a plain GtkButton.

Move more text widget headers into the private header list 2000-09-26 Havoc Pennington <hp@redhat.com> * gtk/Makefile.am (gtk_private_h_sources): Move more text widget headers into the private header list * Makefile.am (pkgconfig_DATA): install pkg-config files * configure.in: add pkg-config files * gdk-2.0.pc.in, gdk-pixbuf.pc.in, gtk+-2.0.pc.in: pkg-config files * gtk/gtkwindow.c (gtk_window_read_rcfiles): Invalidate outstanding icon caches on theme change. * gtk/gtkiconfactory.h, gtk/gtkiconfactory.c: New icon system. Three important types: (GtkIconSource): Specification for creating a pixbuf appropriate for a direction/state/size triplet from a source pixbuf or filename (GtkIconSet): List of GtkIconSource objects that are used to create the "same" icon (e.g. an OK button icon), and cache for rendered icons (GtkIconFactory): Hash from stock ID to GtkIconSet; used to look up the icon set for a given stock ID. GTK maintains a stack of GtkIconFactory to search, and applications or libraries can add additional icon factories on top of the stack * gtk/gtkrc.h, gtk/gtkrc.c: When loading an RcStyle, parse the set of GtkIconSource specified for a given stock ID into a GtkIconSet, and put the GtkIconSet into a GtkIconFactory for the RcStyle, under the specified stock ID. * gtk/gtkstyle.h, gtk/gtkstyle.c: Add a virtual function render_icon used to derive a GdkPixbuf from a GtkIconSource. This allows people to theme how prelight, insensitive, etc. are done. (gtk_style_lookup_icon_set): Look up a stock ID in the list of icon factories for a style, and return the resulting icon set if any. (gtk_style_render_icon): Render an icon using the render_icon method in the GtkStyleClass. * gtk/gtkwidget.h, gtk/gtkwidget.c (gtk_widget_render_icon): Use the style for a given widget to look up a stock ID, get the icon set, and render an icon using the render_icon method of the style * gtk/gtkstock.h, gtk/gtkstock.c: Header with the GtkStockItem type (contains information about a stock item), the built-in stock item IDs, and functions to add/lookup stock items. * gtk/stock-icons/*: Stock icons that come with GTK * gtk/gtkbutton.h, gtk/gtkbutton.c (gtk_button_new_stock): Returns a button based on a GtkStockItem (gtk_button_new_accel): Takes a uline string and accel group, and installs the accelerator. * gtk/gtkimage.h, gtk/gtkimage.c: Make this into a generic image-display widget.

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.
