Values that can be selected for the item in TValueListEditor.
</short>
<descr>
<p>
<var>PickList</var> is a <var>TStrings</var> property which contains values 
that can be selected for the item in <var>TValueListEditor</var>. Values in 
PickList are displayed using a combo-box-style drop down when editing the 
item.
</p>
<p>
Reading the value in PickList ensures that a TStringList class instance is 
assigned for the property. Its OnChange event handler is set to the private 
PickListChange method which adjusts the EditStyle to match the intended usage 
for the item. In other words, an EditStyle of esSimple is changed to 
esPickList when it contains values.
</p>
<p>
Assigning a new TStringList to PickList causes existing values to be 
overwritten. The TValueListEditor (which owns the item) is redrawn when its 
EditorMode property is <b>True</b>.

<element name="TValueListEditor">
<short>
A visual grid control for editing Key-Value pairs.
</short>
<descr>
<p>
<var>TValueListEditor</var> is a <var>TCustomStringGrid</var> descendant 
which implements a grid-style editor control for Key-Value pairs. 
TValueListEditor displays a two column grid where the first column is 
read-only, and lists the key names. The second column is for editing the 
associated values for the key names.
</p>
<p>
TValueListEditor provides properties with the Keys and Values displayed in 
the rows and columns for the control. The Cells property allows access using 
the familiar column and row number mechanism used in grid controls. The 
Strings property allows access to the strings used for the Key and Value in a 
row.
</p>
<remark>
Since version 2.2.0, Keys will no longer allow the name/value separator used 
in the Strings property to be entered as a value in the Key column. When 
entered, focus is moved to the Value column. If pasted into the Key column, 
the value is silently discarded.
</remark>
<p>
The ItemProps property is used to configure the cell editors used for the 
Keys and Values. This includes setting the editor style, edit mask, maximum 
length for the value, a list of selectable pick list values, and a read-only 
flag. Descriptive text for the Key name can also be stored in the ItemProps.
</p>
<p>
Features and behavior for the control can be specified using the Options, 
DisplayOptions, and KeyOptions properties.
</p>
<p>
TValueListEditor implements methods used to perform editing actions in the 
control, including:
</p>
<ul>
<li>Clear</li>
<li>DeleteRow</li>
<li>DeleteColRow</li>
<li>FindRow</li>

<var>AdjustRowCount</var> is a procedure used to set the number of visible 
rows for the control. AdjustRowCount uses the <var>Strings</var> property to 
get the total number of rows needed for the control, including the fixed 
caption row (if needed). When the value differs from <var>RowCount</var>, the 
<var>Row</var> and RowCount properties are updated.
</p>
<p>
AdjustRowCount is called from event handlers when values in Strings or 
<var>TitleCaptions</var> are changed, and when values are included in or

<p>
When Column contains 1 (the Value column), the item definition in ItemProps 
is used to configure the default editor. Its EditStyle is applied by calling 
the EditorByStyle method. For a PickList-style editor, pick list values in 
the item definition are assigned to the combo-box editor control and its 
drop-down row count is set to the value in DropDownRows. The OnGetPickList 
event handler is signalled (when assigned) to get user-defined values in the 
editor control. The read-only status for the editor is updated to reflect the 
value in the item definition.

<descr>
<p>
ParentColor determines if the control should use the Color from the Parent 
control, when enabled. The default value for the property is <b>False</b> in 
TValueListEditor.
</p>
<p>
When this property is <b>True</b>, all changes to the Color of the parent

application, then ParentColor will be automatically set to <b>False</b>.

Using ParentColor when the Color value is clDefault can cause problems in 
resolving the actual color value. To obtain the Color property of a control 
while taking into account clDefault and ParentColor, use the 
GetColorResolvingParent method. This method might return a non-RGB color, but 
will never return clDefault. To obtain a purely RGB result use the 
GetRGBColorResolvingParent method.

<p>
Changing the value in DisplayOptions may cause updates to the 
<var>RowCount</var> and <var>FixedRows</var> properties; they are adjusted to 
reflect use of <var>doColumnTitles</var> in the property. In addition, the 
<var>AutoFillColumns</var> property is updated to reflect use of 
<var>doAutoColResize</var> in the property.
</p>
<p>
The value in DisplayOptions is updated when the value in FixedRows is changed.

<var>KeyOptions</var> is a <var>TKeyOptions</var> property used to control 
actions that can be performed for keys in the control. KeyOptions is a set 
type, and can contain 0 (zero) or more values from the TKeyOption 
enumeration. The default value for the property is an empty set (<b>[]</b>).
</p>

Settings the values in KeyOptions causes the internal UpdatingKeyOptions flag 
to be set. Including the value <var>KeyAdd</var> in KeyOptions requires 
<var>KeyEdit</var> to be added as well. The <var>Options</var> property may 
also be updated to include or exclude the value <var>goAutoAddRows</var> 
based on use of KeyAdd in the property. The internal 
<var>UpdatingKeyOptions</var> flag is cleared prior to exiting from the 
method.

<p>
Changing the value in Options causes additional validation to be performed:
</p>
<ul>
<li>
<var>goColMoving</var> is always excluded from the property value; column 
moving is not a valid operation in TValueListEditor.
</li>
<li>
<var>goAutoAddRowsSkipContentCheck</var> is also excluded from the property.
