/* Images
*
* Gtk.Image is used to display an image; the image can be in a number of formats.
* Typically, you load an image into a Gdk.Pixbuf, then display the pixbuf.
*
* This demo code shows some of the more obscure cases, in the simple
* case a call to the constructor Gtk.Image (string filename) is all you need.
*
* If you want to put image data in your program compile it in as a resource.
* This way you will not need to depend on loading external files, your
* application binary can be self-contained.

* samples/GtkDemo/*.cs: General fixup and cleanup; Remove some gratuitous differences from the C version. Make comment and indent style consistent. Don't use "this." where not needed. Override OnDeleteEvent rather than connecting one's own DeleteEvent signal. * sample/GtkDemo/DemoApplicationWindow.cs (static DemoApplicationWindow): register the Gtk logo icon with StockManager so it shows up correctly in the toolbar. (AddActions): Register the radio items as radio items so they work right. * sample/GtkDemo/DemoHyperText.cs (EventAfter): handle link-clicking from Widget.WidgetEventAfter (as in the C version), rather than ButtonRelease, now that WidgetEventAfter is wrapped. * sample/GtkDemo/DemoImages.cs (DemoImages): use Gtk.Image.LoadFromResource (particularly to make the animation work right). (OnDestroyed): handle clean up (remove the timeout, etc) * sample/GtkDemo/DemoMain.cs (LoadStream): Fix handling of blank lines and whitespace to match the C version. * sample/GtkDemo/DemoPixbuf.cs (Expose): Use System.Runtime.InteropServices.Marshal.Copy() to copy pixbuf.Pixels to pass to DrawRgbImageDithalign, to make this more like the C version (and probably faster?) (timeout): Remove the FIXME since it seems to work now * sample/GtkDemo/DemoStockBrowser.cs: Simplify a bunch. Use reflection to get the C# names of the stock icons rather than trying to correctly re-mangle the ids. Display the Label with the accelerator underlined. * sample/GtkDemo/DemoTextView.cs (AttachWidgets): use Gtk.Image.LoadFromResource, so the image is properly loaded as an animation, not a static image. Don't set the combobox's "Active" property (for consistency with the C version). (InsertText): Fix miscellaneous differences with the C version. Remove some leftover cruft from earlier workarounds for gtk# bugs. * sample/GtkDemo/DemoTreeStore.cs (AddColumns): Make this more like the C version so the checkboxes are sensitized and hidden correctly on a per-row basis. * sample/GtkDemo/DemoUIManager.cs: Make the radio menu items work. * sample/GtkDemo/README: * sample/GtkDemo/TODO: update svn path=/trunk/gtk-sharp/; revision=42481
