Palm OS® Programmer's API Reference

Palm OS® 68K SDK

     

This chapter provides reference material for the insertion point API, declared in the header file InsPoint.h.

For more information on the insertion point, see the section "Insertion Point" in the Palm OS Programmer's Companion, vol. I.

Insertion Point Functions ^TOP^

InsPtEnable Function ^TOP^

Purpose

Enable or disable the insertion point. When the insertion point is disabled, it's invisible; when it's enabled, it blinks.

Declared In

InsPoint.h

Prototype

void InsPtEnable (
   BooleanenableIt
)

Parameters

enableIt
true = enable; false = disable

Returns

Returns nothing.

Comments

This function is called by the Form functions when a text field loses or gains the focus, and by the Windows function when a region of the display is copied (WinCopyRectangle()).

Compatibility

If Palm OS Cobalt Feature Set is present this function is unimplemented.

InsPtEnabled()

InsPtEnabled Function ^TOP^

Purpose

Return true if the insertion point is enabled or false if the insertion point is disabled.

Declared In

InsPoint.h

Prototype

Boolean InsPtEnabled (
   void
)

Parameters

None.

Returns

Returns true if the insertion point is enabled (blinking); returns false if the insertion point is disabled (invisible).

Compatibility

If Palm OS Cobalt Feature Set is present this function is unimplemented.

InsPtEnable()

InsPtGetHeight Function ^TOP^

Purpose

Return the height of the insertion point.

Declared In

InsPoint.h

Prototype

Int16 InsPtGetHeight (
   void
)

Parameters

None.

Returns

Returns the height of the insertion point, in pixels.

Compatibility

If Palm OS Cobalt Feature Set is present this function is unimplemented.

InsPtGetLocation Function ^TOP^

Purpose

Return the screen-relative position of the insertion point.

Declared In

InsPoint.h

Prototype

void InsPtGetLocation (
   Int16*x,
   Int16*y
)

Parameters

x, y
Pointer to top-left position of insertion point's x and y coordinate.

Returns

Returns nothing. Stores the location in x and y.

Comments

This function is called by the Field functions. An application would not normally call this function.

Compatibility

If Palm OS Cobalt Feature Set is present this function is unimplemented.

InsPtSetHeight Function ^TOP^

Purpose

Set the height of the insertion point.

Declared In

InsPoint.h

Prototype

void InsPtSetHeight (
   constInt16height
)

Parameters

height
Height of the insertion point in pixels.

Returns

Returns nothing.

Comments

Set the height of the insertion point to match the character height of the font used in the field that the insertion point is in. When the current font is changed, the insertion point height should be set to the line height of the new font.

If the insertion point is visible when its height is changed, it's erased and redrawn with its new height.

Compatibility

If Palm OS Cobalt Feature Set is present this function is unimplemented.

InsPtGetHeight()

InsPtSetLocation Function ^TOP^

Purpose

Set the screen-relative position of the insertion point.

Declared In

InsPoint.h

Prototype

void InsPtSetLocation (
   constInt16x,
   constInt16y
)

Parameters

x, y
Number of pixels from the left side (top) of the display.

Returns

Returns nothing.

Comments

The position passed to this function is the location of the top-left corner of the insertion point.

This function should be called only by the Field functions.

Compatibility

If Palm OS Cobalt Feature Set is present this function is unimplemented.
