TXLSXHyperlinks üyeleri
| Add(Row, Col, Url) |
Adds a hyperlink with just a URL. Döndürür the new
entry index |
| Add(Row, Col, Url, Display) |
Adds a hyperlink with an explicit display text |
| Add(Row, Col, Url, Display, Tooltip) |
Adds a hyperlink with both display text and tooltip |
| AddInternal(Row, Col, Location, Display, Tooltip) |
Adds an internal anchor hyperlink — jumps to a
Sheet!Cell location (e.g
"Sheet2!A1") elsewhere in the workbook. No worksheet
rels relationship is generated; the <hyperlink>
element carries an inline location attribute. Use
Worksheet.AddHyperlinkToCell(...) for the typical
shortcut |
| IndexOfCell(Row, Col) |
Döndürür the 0-based index of the hyperlink anchored
at the 1-based cell coordinate, or -1 when the cell has
no hyperlink |
| FindAt(Row, Col) |
Döndürür the hyperlink object anchored at the cell,
or nil when no hyperlink is present |
| DeleteAt(Row, Col) |
Deletes the hyperlink anchored at the cell and
returns True; returns False when no matching
hyperlink exists |
| DeleteInRange(Row1, Col1, Row2, Col2) |
Çapası 1 tabanlı, uçları dahil hücre aralığının içinde kalan her köprüyü siler ve kaldırılan sayıyı döndürür. Ters çevrilmiş koordinatlar kabul edilir |
| Delete(Index) |
Deletes the hyperlink at the specified 0-based
collection index |
| Count |
Number of hyperlinks on the worksheet |
| Items[Index] |
Hyperlink at the given 0-based index. Declared as
the default property |
| Clear |
Removes and frees every hyperlink |
