NAME
XmtMsgLinePush(), XmtMsgLinePop() - save and restore messages in an XmtMsgLine widget.SYNOPSIS
void XmtMsgLinePush(Widget w)
void XmtMsgLinePop(Widget w, int when)
ARGUMENTS
INPUTS- w
- An XmtMsgLine widget.
- when
- For XmtMsgLinePop(), specifies when the saved message should be restored.
DESCRIPTION
XmtMsgLinePush() ``pushes'' the currently displayed message onto an internal stack of messages so that it can be later restored with XmtMsgLinePop(). The current contents of the message line are not modified by this call. The message stack grows dynamically, as needed, so any number of messages may be saved on it, and restored later in a last-on-first-off fashion.XmtMsgLinePop() restores the message that was most recently saved (with a call to XmtMsgLinePush()) in the XmtMsgLine widget w. The message is either restored immediately, or at a later time, depending on the value of the when argument. If when is XmtMsgLineNow, then the message is restored immediately. If when is XmtMsgLineOnAction, then the message is restored the next time a user action (a key press or mouse click, for example) occurs. Otherwise, if when is neither of these constants, then it is taken as a time in milliseconds, the message will be restored after the specified time elapses.
If you want a message to be restored either when the user does something, or when a specified time interval elapses, call XmtMsgLinePop() twice, once with the constant XmtMsgLineOnAction, and once with the time interval. If a message line has a pop ``pending'', and the application calls some other XmtMsgLine function (such as XmtMsgLinePush() again) then the pending ``pop'' will be performed immediately instead of waiting for a user action or for time to pass.
