Inheritance diagram for wx.Icon:
An icon is a small rectangular bitmap usually used for denoting a minimized application. It differs from a wx.Bitmap in always having a mask associated with it for transparent drawing. On some platforms, icons and bitmaps are implemented identically, since there is no real distinction between a wx.Bitmap with a mask and an icon; and there is no specific icon format on some platforms (X-based applications usually standardize on XPMs for small bitmaps and icons). However, some platforms (such as Windows) make the distinction, so a separate class is provided.

It is usually desirable to associate a pertinent icon with a frame. Icons can also be used for other purposes, for example with wx.TreeCtrl and wx.ListCtrl.
Icons have different formats on different platforms. Therefore, separate icons will usually be created for the different environments. Platform-specific methods for creating a wx.Icon structure are catered for, and this is an occasion where conditional compilation will probably be required.
Note
Note that a new icon must be created for every time the icon is to be used for a new window. In Windows, the icon will not be reloaded if it has already been used. An icon allocated to a frame will be deleted when the frame is deleted.
Default constructor.
Parameters:
name (string): This can refer to a resource name under MS Windows, or a filename under MS Windows and X. Its meaning is determined by the type parameter.
type (int): One of the following values:
Type Flag |
Description |
---|---|
wx.BITMAP_TYPE_ICO |
Load a Windows icon file. |
wx.BITMAP_TYPE_ICO_RESOURCE |
Load a Windows icon from the resource database. |
wx.BITMAP_TYPE_GIF |
Load a GIF bitmap file. |
wx.BITMAP_TYPE_XBM |
Load an X bitmap file. |
wx.BITMAP_TYPE_XPM |
Load an XPM bitmap file. |
The validity of these flags depends on the platform and wxWidgets configuration
desiredWidth (int): Specifies the desired width of the icon. This parameter only has an effect in Windows (32-bit) where icon resources can contain several icons of different sizes.
desiredHeight (int): Specifies the desired height of the icon. This parameter only has an effect in Windows (32-bit) where icon resources can contain several icons of different sizes.
Returns:
Copies bmp bitmap to this icon. Under MS Windows the bitmap must have mask colour set.
Parameters:

Returns:
bool

Parameters:
name (string): Either a filename or a Windows resource name. The meaning of name is determined by the type parameter.
