class CEditView
__init__(self, templ, doc, frame)
Class CEditView is a view which supports interactive editing of its
contents. An edit view displays multiple lines of text. The edit
view controls its own drawing, so there is no OnDraw() message. An
edit view supports an insertion cursor and a selection.
Text is referenced by line number and by character number, both of which
start at zero. The first character is line 0 character 0. The insertion
cursor is at the character position following the cursor. The selection
is from the first selected character to one past the last character.
For example, if line 123 is "012345678", and the insertion cursor is
between the "4" and "5", the position of the cursor is (123, 5). If
"23456" is selected, the selection is (123, 2, 123, 7).
Instance Variables
wpyText, wpyChildList, wpySizeX/Y, wpyLocX/Y
wpy[HV]ScrollSize, wpy[HV]ScrollWinSize, wpy[HV]ScrollPos
wpyParent
The parent of the view is the frame.
wpyDocument
This is the document which this view is showing.
Methods
__init__(self, templ, doc, frame)
The system creates the view, so the user never calls __init__
directly.
Clear(self)
Clear (delete) the current selection.
ClearAll(self)
Clear (delete) the contents of the view.
EnableWindow(self, enabled)
A disabled edit view is read-only.
GetLine(self, line_num), string
Get the text at line "line_num". Returns a string. The
line_num starts at zero, and is 0, 1, 2, ...
GetLineCount(self), int
Return the number of lines in the view. The minimum is 1.
GetSel(self), tuple
Return the selection as the tuple (line1, char1, line2, char2).
If there is no selection, return the position of the cursor
as (line1, char1, line1, char1).
LineLength(self, line_num), int
Return the length of the line at "line_num".
ReplaceSel(self, text)
Replace the selection with "text". If there is no selection,
then insert "text" at the cursor.
SerializeIn(self, file)
Read in the contents of the file object.
SerializeOut(self, file)
Write the contents of the view to the file object.
SetSel(self, line1, char1, line2, char2)
Set the selection. If line1==line2 and char1==char2, then
set the position of the cursor.
WpyAppend(self, text, newline)
Write the string at the end of the edit view. If newline is
TRUE, add a line break after text. The line break depends
on the platform. It is return/newline on Windows, and newline
alone on Tk.
