- PURPOSE
- The iconobject.datatype has a special API to work with icons. It makes
- both images , tooltypes and many more available.
-
- FUNCTION
- The iconobject.datatype has some special method to draw images and
- writing icons. It is also compatible to gadgets methods. You can use
- datatypes.library or iconobject.library to create objects. The icon-
- object.library is much faster.
- After creating an object the gadget.left and gadget.top fields are
- filled with the saved iconposition. The GA_LEFT,GA_TOP,GA_WIDTH and
- GA_HEIGHT tags are ignored. They have to be set after creating the obj-
- ect if you like to change them.
- Before using the IDTM_Draw method you have to use IDTM_Layout. The
- IDTM_Layout method will generate the images and probably changing the
- size. The extgadget.bounds field of the return object hold the position
- and the whole size (including the text) and the position. The gadget
- size infos are only the image size. The size may change after layouting
- if you setup a inneroffset. The gadget.left/top field may be
- IO_NOPOSITION. If you use an iconobject as gadget you don't need to
- layout it, this will be done automatically.
- The textcolor and the drawmode you like have to be set in the rastport
- before drawing.
-
- CREATING SUBDATATYPES
- OM_NEW
- You have to open the icon and then you should set some
- attributes to the superclass (e.g. Tooltypes). Set the
- position and the size in the gadget struct. If you like
- to have a transparent icon then set the IDTA_Mask_..
- tags before the IDTM_Layout method.
-
- OM_DISPOSE
- Free your icon.
-
- IDTM_Layout
- After calling the superclass you can get the
- gadget.gadgetrender and selectrender. These are filled
- with a pointer to a rastport or NULL. Get the
- IDTA_InnerLeft and IDTA_InnerTop attributes and draw
- your image into the rastport. The bitmap in the rastport
- may be a 15/16 or 24bit bitmap. You can use
- cybergraphics.library to access it. Check the
- layout.flags to know which image you should generate.
-
- IDTM_Write
- Generate a icon from the icon object and write it to
- disk.
-
- IDTA_Extention
- Set the extention of your icons or NULL if they have
- none.

-
- NAME
- iconobject.datatype -- root data type for iconobject.
-
- FUNCTION
- The iconobject.datatype is the super-class of all iconobjects.
-
- METHODS
- OM_NEW -- Create a new iconobject.
-
- OM_GET -- Obtain the value of an attribute.
-
- OM_SET -- Set the values of multiple attributes.
-
- GM_HITTEST -- Determine if the object has been hit with the
- mouse. If the image has a mask, the iconobject will check if the
- click is insite of this mask.
-
- GM_RENDER -- Cause the graphic to render.
-
- IDTM_Layout -- layout the iconobject, it *MUST* be used before using the
- ITDM_Draw method
-
- IDTM_Draw -- draw the whole icon to the rastport given in the io_draw
- struct. The gadget flag SELECTED will determinate the if
- the unselected or selected image will be drawn.
-
- IDTM_Write -- write the icon to disk
-
- IDTM_FindToolType -- find a tooltype
-
- IDTM_GetToolTypeValue -- get a value from a tooltype
-
- IDTM_FreeLayout -- free the layout. This should be used if you change
- the screen. You can use IDTM_Layout after this
- method.
-
-
