|

|
|
// This file contains public declarations for the Bubble-Popup window class.
|
||
|
|
// A bubble-popup provides functionality similar to that of a tooltip,
|
||
|
|
// in that it displays text for a brief period and then hides itself.
|
||
|
|
// This class differs in that it uses DrawText for its output, thus allowing
|
||
|
|
// multi-line text formatted using tabs. Further, the user is required
|
||
|
|
// to tell the bubble-popup when to show itself.
|
||
|
|
//
|
||
|
|
// To create a bubble-popup, call BubblePopup_Create().
|
||
|
|
// This returns an HWND (to be later destroyed using DestroyWindow()).
|
||
|
|
// The text of the bubble-popup can be set and retrieved using WM_SETTEXT
|
||
|
|
// and WM_GETTEXT (and hence the macros {Get,Set}WindowText().
|
||
|
|
//
|
||
|
|
// Set the period for which a popup is active by calling BubblePopup_SetTimeout
|
||
|
|
// and activate the popup by calling BubblePopup_Activate.
|
||
|
|
// While a popup is activated, changes to its text are reflected immediately.
|
||
|
|
// If BubblePopup_Activate is called while the popup is already active,
|
||
|
|
// the countdown (till the window is hidden) is started again.
