A ListEditor is an auxiliary operator for Editor/EditForm
I.E. it works on parameter values expressed as strings
For a parameter which is a list, it may not be edited in once
by just setting a new value (as a string)
Firstly, a list can be long (and tedious to be accessed flat)
then requires a better way of accessing
Moreover, not only its VALUES may be changed (SetValue), but
also its LENGTH : items may be added or removed ...
Hence, the way of editing a parameter as a list is :

A ListEditor is an auxiliary operator for Editor/EditForm
I.E. it works on parameter values expressed as strings
For a parameter which is a list, it may not be edited in once
by just setting a new value (as a string)
Firstly, a list can be long (and tedious to be accessed flat)
then requires a better way of accessing
Moreover, not only its VALUES may be changed (SetValue), but
also its LENGTH : items may be added or removed ...
Hence, the way of editing a parameter as a list is :
- edit it separately, with the help of a ListEditor <br>
- it remains possible to prepare a new list of values apart <br>
- then give the new list in once to the EditForm <br>
An EditList is produced by the Editor, with a basic definition
This definition (brought by this class) can be redefined
Hence the Editor may produce a specific ListEditor as needed
| IFSelect_ListEditor::IFSelect_ListEditor | ( | ) |
Creates a ListEditor with absolutely no constraint
| IFSelect_ListEditor::IFSelect_ListEditor | ( | const Handle< Interface_TypedValue > & | def, |
| const Standard_Integer | max = 0 |
||
| ) |
Creates a ListEditor, for which items of the list to edit are
defined by <def>, and <max> describes max length :
0 (D) means no limit
value > 0 means : no more the <max> items are allowed
|
virtual |
Adds a new item. By default appends (at the end of the list)
Can insert before a given rank <num>, if positive
Returns True when done. False if MaxLength may be overpassed
or if <val> does not satisfy the definition
| void IFSelect_ListEditor::ClearEdit | ( | ) |
Clears all editions already recorded
| Handle_TColStd_HSequenceOfHAsciiString IFSelect_ListEditor::EditedValues | ( | ) | const |
Returns the result of the edition
| Standard_Boolean IFSelect_ListEditor::IsAdded | ( | const Standard_Integer | num | ) | const |
Tells if a value (in edited list) has been added (new one)
| Standard_Boolean IFSelect_ListEditor::IsChanged | ( | const Standard_Integer | num | ) | const |
Tells if a value (in edited list) has been changed, i.e.
either modified-value, or added
| Standard_Boolean IFSelect_ListEditor::IsModified | ( | const Standard_Integer | num | ) | const |
Tells if a value (in edited list) has been modified-value
(not added)
| Standard_Boolean IFSelect_ListEditor::IsTouched | ( | ) | const |
Tells if at least one edition (SetValue-AddValue-Remove) has
been recorded
|
virtual |
Loads a new list to replace the older one, in once ! <br>
By default (can be redefined) checks the length of the list <br>
and the value of each item according to the def <br>
Items are all recorded as Modified <br>
If no def has been given at creation time, no check is done
Returns True when done, False if checks have failed ... a
specialisation may also lock it by returning always False ...
| void IFSelect_ListEditor::LoadModel | ( | const Handle< Interface_InterfaceModel > & | model | ) |
Loads a Model. It is used to check items of type Entity(Ident)
| void IFSelect_ListEditor::LoadValues | ( | const Handle< TColStd_HSequenceOfHAsciiString > & | vals | ) |
Loads the original values for the list
Remark : If its length is mor then MaxLength, editions remain
allowed, except Add
| Standard_Integer IFSelect_ListEditor::NbValues | ( | const Standard_Boolean | edited = Standard_True | ) | const |
Returns count of values, edited (D) or original
| Handle_TColStd_HSequenceOfHAsciiString IFSelect_ListEditor::OriginalValues | ( | ) | const |
Returns the value from which the edition started
|
virtual |
Removes items from the list
By default removes one item. Else, count given by <howmany>
Remove from rank <num> included. By default, from the end
Returns True when done, False (and does not work) if case of
out of range of if <howmany> is greater than current length
| void IFSelect_ListEditor::SetTouched | ( | ) |
Declares this ListEditor to have been touched (whatever action)
|
virtual |
Sets a new value for the item <num> (in edited list)
<val> may be a Null Handle, then the value will be cleared but
not removed
Returns True when done. False if <num> is out of range or if
<val> does not satisfy the definition
| Handle_TCollection_HAsciiString IFSelect_ListEditor::Value | ( | const Standard_Integer | num, |
| const Standard_Boolean | edited = Standard_True |
||
| ) | const |
Returns a value given its rank. Edited (D) or Original
A Null String means the value is cleared but not removed
