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.

Note

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 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. For more information please see Bitmaps and Icons.

Class API¶

class wx.Icon(GDIObject)¶

Possible constructors:

Icon() -> None

Icon(icon) -> None

Icon(name, type=BITMAP_TYPE_ANY, desiredWidth=-1, desiredHeight=-1) ->
     None

Icon(loc) -> None

Icon(bmp) -> None

An icon is a small rectangular bitmap usually used for denoting a minimized application.

Methods¶

__init__(self, *args, **kw)¶

Overloaded Implementations:

__init__ (self)

Default constructor.

Constructs an icon object with no data; an assignment or another member function such as LoadFile must be called subsequently.

Return type:: None

__init__ (self, icon)

Copy constructor.

Parameters:: icon (wx.Icon)
Return type:: None

__init__ (self, name, type=BITMAP_TYPE_ANY, desiredWidth=-1, desiredHeight=-1)

Loads an icon from a file or resource.

Parameters:

name (string) – This can refer to a resource name or a filename under MS Windows and X. Its meaning is determined by the type parameter.
type (BitmapType) – May be one of the wx.BitmapType values and indicates which type of bitmap should be loaded. See the note in the class detailed description. Note that the ICON_DEFAULT_TYPE constant has different value under different wxWidgets ports. See the icon.h header for the value it takes for a specific port.
desiredWidth (int) – Specifies the desired width of the icon. This parameter only has an effect in Windows 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 where icon resources can contain several icons of different sizes.

Return type:

None

See also

LoadFile

__init__ (self, loc)

Loads an icon from the specified location.

Parameters:: loc (wx.IconLocation)
Return type:: None

__init__ (self, bmp)

Construct an Icon from a Bitmap.

Return type:: None

CopyFromBitmap(self, bmp)¶

Copies bmp bitmap to this icon.

Under MS Windows the bitmap must have mask colour set.

Parameters:: bmp (wx.Bitmap)
Return type:: None

LoadFile

CreateFromHICON(self, hicon)¶

MSW-only method to create a wx.Icon from a native icon handle.

Return type:: bool

GetDepth(self)¶

Gets the colour depth of the icon.

A value of 1 indicates a monochrome icon.

Return type:: int

GetHICON(self)¶

MSW-only method to return the native icon handle.

Return type:: int

GetHandle(self)¶

Return type:: int

GetHeight(self)¶

Gets the height of the icon in physical pixels.

Return type:: int

GetWidth , GetLogicalHeight

GetLogicalHeight(self)¶

Gets the height of the icon in logical pixels.

See wx.Bitmap.GetLogicalHeight .

Return type:: float

Added in version 4.1/wxWidgets-3.1.6.

GetLogicalSize(self)¶

Gets the size of the icon in logical pixels.

See wx.Bitmap.GetLogicalSize .

Return type:: wx.Size

Added in version 4.1/wxWidgets-3.1.6.

GetLogicalWidth(self)¶

Gets the width of the icon in logical pixels.

See wx.Bitmap.GetLogicalWidth .

Return type:: float

Added in version 4.1/wxWidgets-3.1.6.

GetScaleFactor(self)¶

Gets the scale factor of this icon.

See wx.Bitmap.GetScaleFactor .

Return type:: float

Added in version 4.1/wxWidgets-3.1.6.

GetSize(self)¶

Gets the size of the icon in physical pixels.

Return type:: wx.Size

IsOk(self)¶

Returns True if icon data is present.

Return type:: bool

LoadFile(self, name, type=BITMAP_TYPE_ANY, desiredWidth=-1, desiredHeight=-1)¶

Loads an icon from a file or resource.

Parameters:

name (string) – Either a filename or a Windows resource name. The meaning of name is determined by the type parameter.
type (BitmapType) – One of the wx.BitmapType values; see the note in the class detailed description. Note that the ICON_DEFAULT_TYPE constant has different value under different wxWidgets ports. See the icon.h header for the value it takes for a specific port.
desiredWidth (int) – Specifies the desired width of the icon. This parameter only has an effect in Windows where icon resources can contain several icons of different sizes.
