PtNotice()

Display a message and wait for acknowledgment

Synopsis:

void PtNotice( PtWidget_t *parent,
        PhPoint_t const *location,
        char const *title,
        PhImage_t const *image,
        char const *message,
        char const *msgFont,
        char const *btnText,
        char const *btnFont,
        int flags );

Arguments:

parent

A pointer to the parent widget of the dialog (usually a window). By setting the flags, you can block the parent and/or position the dialog relative to it.

location

A pointer to a PhPoint_t structure that specifies the location of the dialog relative to the parent or console, depending on the flags. If location is NULL, the dialog is centered.

title

The title for the dialog. If you don't want a title bar, set this argument to NULL.

image

A pointer to a PhImage_t that specifies an icon to be displayed beside the message. If you don't want an icon, set this argument to NULL.

message

The message to display.

msgFont

The font for the message text; the default is TextFont09. You should create the font name by calling PfGenerateFontName().

btnText

The text to be displayed in the button. If this is set to NULL, a default of &OK is used. The btnText argument lets you define a shortcut key -- place an ampersand (&) in front of the character to be used as the shortcut.

btnFont

The font to use in the button. If this is NULL, a default font of TextFont09 is used. You should create the font names by calling PfGenerateFontName().

flags

Flags that specify the behavior for the dialog. This can be up to one of the following:

• Pt_CENTER -- center the dialog.
• Pt_LEFT -- left-align the dialog (the default).
• Pt_RIGHT -- right-align the dialog.

with any combination of the following:

• Pt_BLOCK_ALL -- block all of the application's windows while the dialog is displayed.
• Pt_BLOCK_PARENT -- block the widget specified by the parent argument (if non-NULL).
• Pt_ESC_DISABLE -- disable the ESC key as a means of dismissing the dialog.
• Pt_MODAL -- the same as (Pt_WAIT | Pt_BLOCK_ALL).
• Pt_RELATIVE -- position the dialog relative to the given parent widget. If this bit isn't set or parent is NULL, the dialog is positioned relative to the current console.
• Pt_WAIT -- don't return from the function until the user dismisses the dialog.

Pt_BLOCK_ALL overrides Pt_BLOCK_PARENT.

Library:

ph

Description:

This function displays a message and waits for you to acknowledge it. By setting the flags, you can make PtNotice() work modally, meaning that it doesn't return until you respond.
