锁定或解锁形状

有时，您需要保护工作表中的所有形状，以防止它们被不需要的情况破坏。在这种情况下，您需要锁定指定工作表中的所有形状。

有时，您需要能够修改受保护工作表中的特定形状，在这种情况下，您需要解锁这些形状。

本文将详细介绍如何锁定和解锁指定的形状。

保护指定工作表中的所有形状

要保护指定工作表中的所有形状，请使用Worksheet.Protect(type)方法，如以下示例代码所示。

from aspose.cells import Workbook, FileFormatType,SaveFormat,ProtectionType

text = "This is a test";
workbook = Workbook();
worksheet = workbook.worksheets.get(0);

shape = worksheet.shapes.add_text_box(1, 0, 1, 0, 30, 100);
shape.text = text;

shape = worksheet.shapes.add_rectangle(5, 0, 1, 0, 30, 100);
shape.text = text;

shape = worksheet.shapes.add_button(9, 0, 1, 0, 30, 100);
shape.text = text;

shape = worksheet.shapes.add_oval(13, 0, 1, 0, 50, 100);
shape.text = text;

#Protect all shapes in a specified worksheet 
shape.worksheet.protect(ProtectionType.OBJECTS);#Protects the entire worksheet.
#or shape.worksheet.protect(ProtectionType.All);//Protects all shapes in the specified worksheet.
#or worksheet.protect(ProtectionType.Objects);//Protects the entire worksheet.
#or worksheet.protect(ProtectionType.All);//Protects all shapes in the specified worksheet.

workbook.save(r"Locked.xlsx", SaveFormat.XLSX);

解锁受保护工作表中的指定形状

要在受保护的工作表中解锁指定的形状，请使用shape.is_locked，如以下示例代码所示。

注意：当工作表受到保护时，shape.is_locked只有意义。

from aspose.cells import Workbook, FileFormatType,SaveFormat,ProtectionType

workbook = Workbook(r"Locked.xlsx")

#Get protected worksheet
worksheet = workbook.worksheets[0]

#Get the specified shape to be unlocked
shape = worksheet.shapes[0]

#Unlock the specified shape
if (not worksheet.protection.allow_editing_object and shape.is_locked):
    shape.is_locked = False;


workbook.save(r"UnLocked.xlsx", SaveFormat.XLSX);
