Remarks
The CMFCTasksPane class implements the following functionality:
Items can be grouped and each item grouping can have an associated caption.
Item groupings can be collapsed or expanded.
An icon can be assigned to each item in the task pane.
Individual items can be associated with a command ID which executes when a user clicks the item. When the click occurs, the WM_COMMAND message is sent to the owner of the task pane control.
To use the CMFCTasksPane control in your application, follow these steps:
Embed a CMFCTasksPane object into the main frame window class.
When processing the WM_CREATE message, call the Create method. You can use the regular CControlBar styles. For more information, see CControlBar::Create.
Call the CMFCTasksPane::AddGroup method to add various groups.
Call the CMFCTasksPane::AddTask, CMFCTasksPane::AddLabel or CMFCTasksPane::AddMRUFilesList member functions to add new items (tasks) to each group.
Call CMFCTasksPane::EnableGroupCollapse to specify whether item groups can collapse.
The following illustration shows a typical task pane control. The first group is a special group and its caption is a darker color. The third group is collapsed. The last group is aligned to the bottom of the task pane and has no caption, and the last task in the group is a simple label:

You can customize the appearance of the task pane by adjusting various margins and offsets. The following illustration clarifies the meaning of these variables:

Example
The following example demonstrates how to construct a CMFCTasksPane object and use various methods in the CMFCTasksPane class. The example shows how to enable the collapsing of task groups, enable the drop-down menus on the Next and Previous navigation buttons, enable the scroll buttons instead of a scroll bar, enable the word wrapping for the text in labels, set the caption name of the task pane, set the text color for a group caption, and set the horizontal and vertical margins.
CMFCTasksPane* tPane = new CMFCTasksPane();
tPane->EnableGroupCollapse(true);
tPane->EnableHistoryMenuButtons(true);
tPane->EnableScrollButtons(true);
tPane->EnableWrapLabels(true);
tPane->SetCaption(_T("Task Pane"));
tPane->SetGroupTextColor(0,RGB(0,0,128));
tPane->SetHorzMargin(15);
tPane->SetVertMargin(15);
tPane->Update();
