Overview of Item Types

Handle Items

Items of type handle are special items that are designed to be used for selection handles around items when manipulating them within an application. Handles are similar to rectangles, except unlike every other item in Pad++, handles do not zoom. Handles are always rendered at the same size. Handles, however, do slide around like other items. They just don't zoom. Handles default to being five by five pixels, but this can be changed with the -width and -height itemconfigure options.

Handles are created with widget commands of the following form:

pathName create handle [option value option value ...]
There may be any number of option-value pairs, each of which sets one of the configuration options for the item. These same option-value pairs may be used in itemconfigure widget commands to change the item's configuration. The following options are supported for handles:

[29] -fill color

(available only for handle, HTML, Polygon, Portal and Rectangle item types)

Fill the background of the item with color, which may be specified in any of the forms accepted by Tk_GetColor. If color is "none", the background will not be drawn. It defaults to the red.

[30] -pen color

(available only for handle, line, polygon, portal, rectangle, spline, text and textfile item types)

Color specifies a color to use for drawing the item; it may have any of the forms acceptable to Tk_GetColor. It may also be "none", in which case the outline will not be drawn. This option defaults to black.
