Description
The class uses binding to windows events and monitors WM_CREATE, WM_SHOWWINDOW and WM_DESTROY events. If the window is a form, a button is automatically added with form caption as text. Also, at startup, add buttons for all active forms Usage: Public otb SET CLASSLIB TO taskbar.vcx otb = CREATEOBJECT('taskbar') An application object or _screen property can be also used to store the reference The class show/hide itself as necessary (if there are no active forms is not visible), automatically expand to accomodate the number of buttons. The .singleLine property controls diplay of multiple lines. If there are many lines of buttons but .singleLine = .T., a spinner control will be made visible and can be used to change current line of buttons on toolbar. If one of the forms has a .shortCaption property, it will be used instead of Caption to disply text on toolbar button. Update: lHideFormsOnMinimize property right click context menu form's icon is copied into an temporary image and used for associated button. new taskbarIcon property for alternative taskbar button image fixed right click context menu popup

Excelent class!! You could add to init code of taskbar something like this: SET CLASSLIB TO (This.ClassLibrary) ADDITIVE This way the taskbar can be used like this: oTaskBar=NEWOBJECT("taskbar","taskbar") How about adding support for minimized forms? When a form gets minimized, hide it , we already have the button in the new cute taskbar. When clicked in taskbar, restore it and show it again. Just one or two more window messages to watch for. If you hide all windows using the "Window" menu, the form that was last hidden stays selected. That can be fixed with .Value = 0 in the optionbutton. And how about using the forms icons in the buttons? That would be great. Now if we could only have a small sizing grip picture on the left, CAPS and NUM indicator, space for statusbar messages, and we can replace the statusbar with a nice taskbar/statusbar combo.

This class workds only ion VFP 9. The message you mention is usually triggered by the _memberdata property for classes in earlier versions. Dorin Vasilescu, November 13, 2005
