Radio button control window class.

The PMCheckBox class creates and manages check box control windows. A check box is a square box with associated text that represents a choice. When a user selects the choice, the check box is filled to indicate that the choice is selected. If the user selects the check box again, the choice is deselected.

You can construct and destruct objects of this class.

Source:

pm_checkbox.h:55

Params:

hparent	Specifies the parent-window handle.
id	Specifies the identity of the child window.

Code:

public PMCheckBox (	HWND hparent ,
	SHORT id )

Constructs the check box control window.

Source:

pm_checkbox.h:101

Params:

id	Specifies the window identifier.
text	Specifies the window text.
hparent	Specifies the parent-window handle.
x,y,cx,cy	Specifies the window shape.
style	Specifies the window style: BS_3STATE Creates a three-state check box (see also BS_CHECKBOX). When the user selects the check box, it sends a WM_CONTROL message to the owner window. The owner should set the check box to the appropriate state: selected, unselected, or halftone. BS_AUTO3STATE Creates an auto-three-state check box (see also BS_CHECKBOX). When the user selects the check box, the system automatically sets the check box to the appropriate state: selected, unselected, or halftone. BS_AUTOCHECKBOX Creates an auto-check box (see also BS_CHECKBOX). The system automatically toggles the check box between the selected and unselected states each time the user selects the box. BS_AUTOSIZE Creates a button that is sized automatically to ensure that the contents fit. Note: The cx or cy parameter of must be specified as -1 to implement the autosize feature. BS_CHECKBOX Creates a check box-a small square that has text displayed to its right. When the user selects a check box, the check box sends a WM_CONTROL message to the owner window. The owner window should toggle the check box between selected and unselected states.
