The CreatePopupTrigger Method creates a popup trigger that displays a pop-up list when the user taps it. The currently selected item appears to the right of the trigger.
Syntax
public WaveLinkWidget CreatePopupTrigger(int XCoord, int YCoord, intWidth, int Height, String menuName, int initialOption, WaveLinkWidgetCollection targetCollection)
throws WaveLinkError
Parameters
|
XCoord |
The starting left coordinate of the widget |
|
YCoord |
The starting top coordinate of the widget |
|
Width |
The horizontal extent of the widget |
|
Height |
The vertical extent of the widget |
|
menuName |
The name of the WaveLinkMenu configuration associated with the widget |
|
initialOption |
The initial menu-index value of the widget (for example, passing a 1 indicates the first menu entry in the WaveLinkMenu configuration) |
|
targetCollection |
The name of the collection that will contain the widget |
Returns
A pointer to the popup trigger widget
Throws
WaveLinkError
Remarks
The popup trigger populates its menu options with a stored WaveLinkMenu configuration. The menu must be stored on the device before the popup trigger can access it. The widget returns the menu index of the user-selected option.
The CreatePopupTrigger Method automatically stores the menu name associated with the current widget in the SpecialString Property.
For the Width and Height parameters, pass a value of 0 to set the width or height automatically. Set the size of the widget to AUTOSIZE by setting both the width and height to zero (0).
We recommend that you use the AUTOSIZE setting for the height and width of the popup trigger. Using a value other than AUTOSIZE does not change the size of the widget, only the extent of the clickable area surrounding it.
Example
WaveLinkFactory factoryIface = new WaveLinkFactory();
WaveLinkWidgetCollection colIface = new WaveLinkWidgetCollection();
WaveLinkIO ioIface = new WaveLinkIO();
WaveLinkMenu mnuIface = new WaveLinkMenu();
try {
// Create the menu that appears in the widget
mnuIface.ResetMenu();
mnuIface.MenuWidth(18);
mnuIface.AddOption("Basic Car Wash");
mnuIface.AddOption("Basic Wash/Wax");
mnuIface.AddOption("Carnuba Wax");
mnuIface.AddOption("Interior Clean");
mnuIface.AddOption("Full Detail");
mnuIface.AddOption("Special Detail");
mnuIface.AddOption("Device Version");
mnuIface.AddOption("Exit");
mnuIface.StoreMenu("MainMenu");
.
.
.
ioIface.RFPrint(0, 0, "Select Wash:", WaveLinkIO.WLCLEAR);
factoryIface.CreatePopupTrigger(3, 5, 0, 0, "MainMenu", 1, colIface);
colIface.StoreWidgets();
}
catch (WaveLinkError wlErr) {
//Do error handling
}
