XmtDisplayWorkingDialog(3) Library Functions Manual XmtDisplayWorkingDialog(3) NAME XmtDisplayWorkingDialog(), XmtHideWorkingDialog() - display or hide a ``please wait'' dialog box. SYNOPSIS #include <Xmt/Dialogs.h> Widget XmtDisplayWorkingDialog(Widget w, String dialog_name, String message_default, String scale_label_default, String but- ton_label_default, int scale_min, int scale_max, Boolean show_scale, Boolean show_button) void XmtHideWorkingDialog(Widget w) ARGUMENTS INPUTS w The shell widget over which the dialog will be popped up or popped down, or any descendant of that shell. dialog_name The name for this instantiation of the dialog. This name is used to look up the message and title resources for the dialog. NULL may be specified, but will result in a dialog that cannot be customized through the resource manager. message_default The default message to be used if no dialog_name is pro- vided, or if no message is found under that name in the resource database. scale_label_default The string to display to the left of the XmScale widget if no overriding value is found in the resource database. Specify NULL for the default label. button_label_default The string to display in the single XmPushButton widget of the dialog if no overriding value is found in the resource database. Specify NULL for the default label. scale_min The minimum value to be displayed by the XmScale widget. scale_max The maximum value to be displayed by the XmScale widget. show_scale Whether the XmScale widget (and its associated text label) should be displayed in the dialog. show_button Whether the XmPushButton widget should be displayed in the dialog. RETURNS A pointer to the XmtWorkingBox widget which was popped up by the function. DESCRIPTION The XmtWorkingBox widget is designed to display ``Busy; please wait'' dialog boxes to the user. XmtDisplayWorkingDialog() and XmtHideWorking- Dialog() provide a simplified interface for handling these dialogs-they automatically create the required dialog widget and cache it for subse- quent reuse. XmtDisplayWorkingDialog() displays a modal XmtWorkingBox dialog con- taining a message and a ``working'' icon. The dialog is intended to be posted while the application is performing some time consuming task during which it will not be responding to user input events. It option- ally (depending on show_scale) contains an XmScale widget which can be used to provide feedback to the user about the progress of whatever task is underway. A label, ``% Complete:'' by default, appears to the left of the XmScale widget. The minimum and maximum bounds for the XmScale slider are specified by scale_min and scale_max. The working dialog also contains an optional (depending on show_button) XmPushBut- ton widget which can be periodically polled to see if the user wants to abort the task. The default label for the button is Stop. XmtDisplayWorkingDialog() returns the XmtWorkingBox widget of the dia- log. This value can be used in subsequent calls to XmtWorking- BoxSetScaleValue() and XmtWorkingBoxHandleEvents() to update the XmScale slider value and to poll the XmPush Button widget of the dia- log. XmtDisplayWorkingDialog() calls XmtWaitUntilMapped() before returning to ensure that the dialog box is visible to the user before returning to the calling function which will generally perform some time consum- ing task without handling events. XmtHideWorkingDialog() pops down any XmtWorkingBox dialog that was posted over the shell of w by XmtDisplayWorkingDialog(). Note that w is the same widget passed to XmtDisplayWorkingDialog() (or any other descendant of the shell); not the widget returned by XmtDisplayWorking- Dialog(). WIDGETS XmtDisplayWorkingDialog() creates a single XmtWorkingBox dialog for each screen it is called on, and caches that dialog for reuse by subse- quent calls to the function. The name of the XmtWorkingBox is ``xmt- WorkingDialog'', and the name of its XmDialogShell parent is ``xmtWork- ingDialogShell''. If you set resources on these widgets note that, because of the dialog caching, they will affect all instantiations of the working dialog. Customization You can also customize individual instantiations of working dialogs by specifying the dialog_name argument to XmtDisplayWorkingDialog(). The resources are looked up as a subpart of the shell widget of w. The name of the subpart is given by dialog_name, and the class of the subpart is ``XmtWorkingDialog''. The table lists the resources that are looked up, their default values, and how they are used. +-------------+--------------------------------------+---------------------+ | Name | Default | Purpose | +-------------+--------------------------------------+---------------------+ | message | message_default | the message to be | | | | displayed. | +-------------+--------------------------------------+---------------------+ | scaleLabel | scale_label_default or "% Complete:" | the label for the | | | | scale widget. | +-------------+--------------------------------------+---------------------+ | buttonLabel | button_label_default or "Stop" | the button label. | +-------------+--------------------------------------+---------------------+ | title | "Working" | text for the dialog | | | | titlebar. | +-------------+--------------------------------------+---------------------+ SEE ALSO Chapter 31, Busy States and Background Work, XmtWorkingBox, XmtWaitUntilMapped(), XmtWorkingBoxHandleEvents(), XmtWorkingBoxSetScaleValue().
