The CMFCTasksPaneTaskGroup class is a helper class used by the CMFCTasksPane control. Objects of type CMFCTasksPaneTaskGroup represent a task group. The task group is a list of items that the framework displays in a separate box that has a collapse button. The box can have an optional caption (group name). If a group is collapsed, the list of tasks is not visible.

CMFCTasksPaneTaskGroup::CMFCTasksPaneTaskGroup

Constructs a CMFCTasksPaneTaskGroup object.

CMFCTasksPaneTaskGroup(
    LPCTSTR lpszName,  
    BOOL bIsBottom,  
    BOOL bIsSpecial=FALSE,  
    BOOL bIsCollapsed=FALSE,  
    CMFCTasksPanePropertyPage* pPage=NULL,  
    HICON hIcon=NULL);

Parameters

lpszName
Specifies the name of the group in the group caption.

bIsBottom
Specifies whether the group is aligned to the bottom of the task pane control.

bIsSpecial
Specifies whether the group is designated as special and thus, whether the group caption is filled with a different color.

bIsCollapsed
Specifies whether the group is collapsed.

pPage
Specifies the property page that this task group belongs to.

hIcon
Specifies the icon that displays in the group caption.

Remarks

CMFCTasksPaneTaskGroup::m_bIsBottom

Determines whether the task group is aligned to the bottom of the task pane control.

BOOL m_bIsBottom;

Remarks

Only one group can be aligned to the bottom of the task pane control. This task group must be added last. For more information, see CMFCTasksPane::AddGroup.

CMFCTasksPaneTaskGroup::m_bIsCollapsed

Determines whether the task group is collapsed.

BOOL m_bIsCollapsed;

Remarks

You can enable or disable the ability to collapse groups on the task pane by calling CMFCTasksPane::EnableGroupCollapse.

CMFCTasksPaneTaskGroup::m_bIsSpecial

Determines whether the task group is special and whether the caption for a special task group should be identified by a different color.

BOOL m_bIsSpecial;

Remarks

If your application is using the Windows XP visual theme and m_bIsSpecial is FALSE, the framework calls DrawThemeBackground with the EBP_NORMALGROUPBACKGROUND flag. If m_bIsSpecial is TRUE, the framework calls DrawThemeBackground with the EBP_SPECIALGROUPBACKGROUND flag.

CMFCTasksPaneTaskGroup::m_lstTasks

Contains the internal list of tasks.

CObList m_lstTasks;

Remarks

To fill this list, call CMFCTasksPane::AddTask.

CMFCTasksPaneTaskGroup::m_rect

Specifies the bounding rectangle of the group caption.

CRect m_rect;

Remarks

This value is automatically calculated by the framework.

CMFCTasksPaneTaskGroup::m_rectGroup

Specifies the bounding rectangle of the group.

CRect m_rectGroup;

Remarks

This value is calculated automatically by the framework.

CMFCTasksPaneTaskGroup::m_strName

Specifies the name of the group.

CString m_strName;

Remarks

If this value is empty, the group caption is not displayed and the group cannot be collapsed.

CMFCTasksPaneTaskGroup::SetACCData

Determines the accessibility data for the current task group.

virtual BOOL SetACCData(
    CWnd* pParent,  
    CAccessibilityData& data);

Parameters

[in] pParent
Represents the parent window of the current task group.

[out] data
An object of type CAccessibilityData that is populated with the accessibility data of the current task group.

Return Value

TRUE if the data parameter was successfully populated with the accessibility data of the current task group; otherwise, FALSE.
