ملاحظات الاستخدام

Call this method after creating the target field and before EndDoc
The method is useful when code uses THPDFPage.AddTextField, AddCheckBox, AddRadioButton, AddComboBox, or AddListBox instead of the wrapper-returning Create... helpers
For wrapper-based code, use THPDFAcroFormField.SetTooltip to configure the field directly from the returned wrapper
An unknown field name raises the same field lookup exception used by the form-field additional-action helpers

Example

HPDF.BeginDoc;
HPDF.AddPage;
HPDF.CurrentPage.AddTextField('CustomerName', '', Rect(50, 100, 250, 120));
HPDF.SetFormFieldTooltip('CustomerName', 'Customer name');
HPDF.EndDoc;
