Remarks
Use CMFCToolTipCtrl Class, CMFCToolTipInfo, and CTooltipManager Class together to implement customized tooltips in your application. For an example of how to use these tooltip classes, see the CMFCToolTipCtrl Class topic.
Example
The following example demonstrates how to set the values of the various member variables in the CMFCToolTipInfo class.
CMFCToolTipInfo *params = new CMFCToolTipInfo();
params->m_bBoldLabel = FALSE;
params->m_bDrawDescription = FALSE;
params->m_bDrawIcon = FALSE;
params->m_bRoundedCorners = TRUE;
params->m_bDrawSeparator = FALSE;
params->m_clrFill = RGB(255, 255, 255);
params->m_clrFillGradient = RGB(228, 228, 240);
params->m_clrText = RGB(61, 83, 80);
params->m_clrBorder = RGB(144, 149, 168);

Requirements
Header: afxtooltipctrl.h
CMFCToolTipInfo::m_bBalloonTooltip
Specifies the display style of all tooltips.
BOOL m_bBalloonTooltip;
Remarks
TRUE indicates that tooltips use the balloon style, FALSE indicates that tooltips use the rectangular style.
CMFCToolTipInfo::m_bBoldLabel
Specifies whether the font of the tooltip text is bold.
BOOL m_bBoldLabel;
Remarks
Set this member to TRUE to display tooltip text with bold font, or FALSE to display tooltip labels with non-bold font.
CMFCToolTipInfo::m_bDrawDescription
Specifies whether each tooltip displays description text.
BOOL m_bDrawDescription;
Remarks
Set this member to TRUE to display the description, or FALSE to hide the description. You can specify the description on a tooltip by calling CMFCToolTipCtrl::SetDescription
CMFCToolTipInfo::m_bDrawIcon
Specifies whether all tooltips display icons.
BOOL m_bDrawIcon;
Remarks
Set this member to TRUE to display an icon on each tooltip, or FALSE to display tooltips without icons.
CMFCToolTipInfo::m_bDrawSeparator
Specifies whether each tooltip has a separator between its label and its description.
BOOL m_bDrawSeparator;
Remarks
Set this member to TRUE to display separator between tooltip label and description, or FALSE to display tooltips with no separator.
CMFCToolTipInfo::m_bRoundedCorners
Specifies whether all tooltips have rounded corners.
BOOL m_bRoundedCorners;
Remarks
Set this member to TRUE to display rounded corners on tooltips, or FALSE to display rectangular corners on tooltips.
CMFCToolTipInfo::m_clrBorder
Specifies the color of the borders on all tooltips.
COLORREF m_clrBorder;
CMFCToolTipInfo::m_clrFill
Specifies the color of tooltip backgrounds.
COLORREF m_clrFill;
Remarks
If CMFCToolTipInfo::m_clrFillGradient is -1, the tooltip background color is m_clrFill. Otherwise, m_clrFill specifies the color of the beginning of the gradient and m_clrFillGradient specifies the color of the end of the gradient. CMFCToolTipInfo::m_nGradientAngle determines the direction of the gradient.
CMFCToolTipInfo::m_clrFillGradient
Specifies the end color for a gradient background for tooltips.
COLORREF m_clrFillGradient;
Remarks
If m_clrFillGradient is -1, there is no gradient. Otherwise, the gradient initial color is specified by CMFCToolTipInfo::m_clrFill and the gradient finish color is specified by m_clrFillGradient. CMFCToolTipInfo::m_nGradientAngle determines the direction of the gradient.
CMFCToolTipInfo::m_clrText
Specifies text color of all tooltips.
COLORREF m_clrText;
CMFCToolTipInfo::m_nGradientAngle
Specifies the angle at which a gradient is drawn on the background of tooltips.
int m_nGradientAngle;
Remarks
m_nGradientAngle specifies the angle, in degrees, that the gradient on the background of tooltips is offset from horizontal. If m_nGradientAngle is 0, the gradient is drawn from left to right. If m_nGradientAngle is between 1 and 360, the gradient is rotating clockwise by that number of degrees. If m_nGradientAngle is -1, which is the default value, the gradient is drawn from top to bottom. This is the same as setting m_nGradientAngle to 90.
CMFCToolTipInfo::m_clrFill clrFill specifies the color of the beginning of the gradient and CMFCToolTipInfo::m_clrFillGradient clrFillGradient specifies the color of the end of the gradient. If m_clrFillGradient is -1, there is no gradient.
CMFCToolTipInfo::m_nMaxDescrWidth
Specifies the maximum width of the description that it displayed in each tooltip. If the description width exceeds the specified value, the text is wrapped.
int m_nMaxDescrWidth;
CMFCToolTipInfo::m_bVislManagerTheme
Specifies whether the visual manager of the application controls the appearance of all tooltips.
BOOL m_bVislManagerTheme;
Remarks
If m_bVislManagerTheme is TRUE, every tooltip requests a new CMFCToolTipInfo from the visual manager of the application before they appear on the screen, and uses the values in that object to determine their appearance. The other members of your CMFCToolTipInfo are ignored.
