CTaskDialog::SetFooterIcon
Updates the footer icon of the CTaskDialog.
void SetFooterIcon(
HICON hFooterIcon
);
void SetFooterIcon(
LPCWSTR lpszFooterIcon
);
Parameters
[in] hFooterIcon
The new icon for the CTaskDialog.[in] lpszFooterIcon
The new icon for the CTaskDialog.
Remarks
The footer icon is displayed on the bottom of the CTaskDialog Class. It can have associated footer text. You can change the footer text with CTaskDialog::SetFooterText.
This method throws an exception with the ENSURE (MFC) macro if the CTaskDialog is displayed or the input parameter is NULL.
A CTaskDialog can only accept an HICON or LPCWSTR as a footer icon. This is configured by setting the option TDF_USE_HICON_FOOTER in the constructor or CTaskDialog::SetOptions. By default, the CTaskDialog is configured to use LPCWSTR as the input type for the footer icon. This method generates an exception if you try to set the icon using the inappropriate type.
Example
// TODO: Replace the strings below with the appropriate message,
// main instruction, and dialog title
CString message("This is an important message to the user.");
CString mainInstruction("Important!\nPlease read!");
CString title("Alert Dialog");
CTaskDialog taskDialog(message, mainInstruction, title,
TDCBF_YES_BUTTON | TDCBF_NO_BUTTON | TDCBF_CANCEL_BUTTON );
// Setting new information to be able to reuse the dialog resource
taskDialog.SetWindowTitle(L"New title for the task dialog");
taskDialog.SetContent(L"New message to show the user.");
taskDialog.SetMainInstruction(L"Even more important!");
taskDialog.SetMainIcon(TD_ERROR_ICON);
taskDialog.SetDialogWidth(300);
// Add a footer
taskDialog.SetFooterText(L"Footer information for the dialog.");
taskDialog.SetFooterIcon(TD_INFORMATION_ICON);
// Add expansion information
taskDialog.SetExpansionArea(L"Additional information\non two lines.",
L"Click here for more information.",
L"Click here to hide the extra information.");
// Change the options to show the expanded information by default.
// It is necessary to retrieve the current options first.
int options = taskDialog.GetOptions();
options |= TDF_EXPANDED_BY_DEFAULT;
taskDialog.SetOptions(options);
taskDialog.DoModal();
