<element name="TCustomFloatSpinEdit">
<short>
The base class for a spin edit control using a floating point value.
</short>
<descr>
<p>
<var>TCustomFloatSpinEdit</var> is a <var>TCustomEdit</var> descendant which 
implements the base class for the float-based spin edit control. It provides 
an edit control where the Float value can be entered directly, and up / down 
buttons which can be used to increment or decrement the value for the control.
</p>
<p>
Use the Value property to assign a floating point value to the control as a 
Double type. Value is a 64-bit real type in the range 5.0E-324 .. 1.7E308 
(inclusive), and allows up to 15-16 digits of precision (15 digits for a 
negative value).
</p>
<p>
At run-time, setting Value to a number outside of the range for the real type 
causes Value to be updated. When neither MinValue nor MaxValue have been 
assigned, either -Inf or +Inf is displayed as the value for the control. If 
either MinValue or MaxValue has been given an explicit non-default value, the 
Value property is updated with corresponding range limit.
</p>
<p>
In LCL version 3.0, the floating point property editor will not allow an 
invalid value to be stored in the Value property at design-time. An error is 
raised (and handled) with the message 'Property value out of range', and the 
Value property is not updated.
</p>
<p>
LCL versions prior to 3.0 allowed the values +Inf, -Inf, and NaN to be 
assigned as the property value. These values are no longer supported in LCL 
version 3.0 and later.
</p>
<p>
Use the MinValue and MaxValue properties to define the lower and upper limits 
for the Value in the control. Like Value, they are implemented as a Double 
type with the same range limits. An invalid value causes the property to be 
set to the corresponding range limit for the real type.
</p>
<p>
Use the DecimalPlaces property to specify the number of decimal digits 
displayed for a value not represented using the radix/precision/exponent 
format for the IEE 754 value.
</p>
<p>
Use the Increment property to set the value added to or subtracted from the 
control Value when the up or down buttons are clicked.

<element name="TCustomFloatSpinEdit.Change">
<short>
Updates Modified prior to sending control messages and signalling OnChange 
handler(s).
</short>
<descr>
<p>
<var>Change</var> is an overridden method in <var>TCustomFloatSpinEdit</var>. 
It ensures that the value in <var>Modified</var> is updated when the 
widgetset class applies a new value for the control. An internal flag is used 
to determine if Modified is set to <b>False</b> prior to calling the 
inherited Change method. The flag is set when a new value is applied to the 
Value property in program code (instead of using the UI elements for the 
control). This is performed here because the widgetset class calls Changed 
and not TextChanged.
</p>
<p>
Change calls the inherited method where the CM_CHANGED control message is 
posted, and assigned OnChange handlers are signalled for the control.

<element name="TCustomFloatSpinEdit.EditingDone">
<short>
Performs actions when editing has been completed for the control.
</short>
<descr>
<p>
EditingDone is an overridden method in TCustomFloatSpinEdit. It ensures that 
the control is updated when editing has been completed.
</p>
<p>
EditingDone calls the UpdateControl method to normalize and validate the 
control Value using the assigned range in MinValue and MaxValue. This 
includes calling GetLimitedValue to update the control Value when both 
MinValue and MaxValue contain a valid range. The value in the widgetset class 
is updated when component streaming is not active, and the control is not 
being freed.
</p>
<p>
EditingDone calls the inherited method to signal the OnEditingDone event 
handler (when assigned) when ReadOnly is <b>False</b>.
</p>
<p>
EditingDone is called from the KeyUpAfterInterface method in TCustomEdit when 
the Enter (VK_RETURN) key code is handled for the control. It also occurs 
when the focused control has been changed.
</p>
</descr>
<version>
The method override was added in LCL version 2.2.1.

<p>
<var>Loaded</var> calls the inherited method on entry to determine the size 
for the control (and its children) and to apply property values inherited 
from the parent control (when assigned). Loaded calls the private 
<var>UpdateControl</var> method when the internal update flag has been set 
for the control.

<element name="TCustomFloatSpinEdit.KeyPress">
<short>Handles key press events for the control.</short>
<descr>
<p>
<var>KeyPress</var> is an overridden method used to handle key press events 
for the control. KeyPress calls the inherited method on entry. If the 
character in <var>Key</var> is not handled in the ancestor class, the 
argument is examined to determine if it is valid for the control. If Key is 
not a valid character, it is set to <b>#0</b> to ignore the key press event.
</p>
<p>
KeyPress disallows any value in Key that is not a numeric digit, sign 
character ('+' or '-'), scientific exponentiation symbol ('E' or 'e'), or 
decimal point character ('.' or ','). The decimal point is automatically 
converted to the value used in the <var>DefaultFormatSettings</var> variable 
from the RTL. The decimal point is not allowed when <var>Decimals</var> is 
set to <b>0</b> (<b>zero</b>).
</p>
<p>
KeyPress does not ensure that the value in Key is valid for a specific 
position in the control value. It does not guarantee that sign indicators are 
used only at the start of the control value. Nor does it guarantee that a 
decimal point character is not used more than once in the entered value. This 
is implemented in a manner that is Delphi compatible.
</p>
<p>
Tab (<b>#9</b>), BackSpace (<b>#8</b>), Cut (<b>^X</b>), Paste (<b>^V</b>), 
Copy (<b>^C</b>), and Undo (<b>^Z</b>) characters are allowed in Key so that 
they may be applied in inherited methods for the control.

<p>
The return value is set to AValue and limited to the range in the MinValue

than MinValue. No constraints are applied when MinValue and MaxValue have the 
the same value, or when MaxValue is smaller than MinValue.

Delphi does not constrain the value when MinValue and MaxValue are the same, 
but does if MaxValue is smaller than MinValue.

<short>
Indicates whether the value for the control can be entered directly into its

<descr>
<p>
<var>EditorEnabled</var> is a <var>Boolean</var> property which indicates if 
the <var>Value</var> for the control can be input directly. When set to 
<b>True</b>, the edit box is enabled. When set To <b>False</b>, only the up 
and down arrow buttons can be used to change the Value for the control.
</p>
<p>
The default value for the property is <b>True</b>. Changing the value for the 
property causes the widgetset class to be notified when the Handle for the 
control has been allocated.
</p>
<p>
EditorEnabled is independent of the settings in the <var>ReadOnly</var> and 
<var>Enabled</var> properties. When ReadOnly is set to <b>True</b>, the Value 
for the control cannot be modified using either the edit box or the up / down 
buttons. When Enabled is set to <b>False</b>, the control cannot be given 
focus or modified.
</p>
<remark>
Disabling the edit box requires support from the underlying widgetset class. 
It may not be supported or implemented for all widgetsets  / platforms. In 
the current LCL version, it is implemented for the Windows and Windows CE 
platforms.

<element name="TCustomFloatSpinEdit.Value">
<short>
The floating point value for the spin edit control.
</short>
<descr>
<p>
<var>Value</var> is a Double property which contains the floating point value 
for the spin edit control. It can be modified using the UI elements for the 
control (up and down buttons, up and down cursor keys, or the edit box for 
the control). It can also be assigned directly in program code.
</p>
<p>
Value is a 64-bit real type in the range 5.0E-324 .. 1.7E308 (inclusive), and 
allows up to 15-16 digits of precision (15 digits for a negative value).
</p>
<p>
Changing the value for the property causes the <var>Text</var> for the 
control to be checked for a valid numeric representation for the property. If 
the new property value is the same as the existing value, no actions are 
performed.
</p>
<p>
When the property value has been stored, internal flags are set to ensure 
that <var>Modified</var> is updated accordingly and the private 
<var>UpdateControl</var> method is called. If the handle for the control has 
been allocated, the <var>Change</var> method is called to post a 
<b>CM_CHANGED</b> control message and signal <var>OnChange</var> handler(s) 
assigned for the control.
</p>
<p>
When changed, Value is constrained to the range defined in the 
<var>MinValue</var> and <var>MaxValue</var> properties (when assigned). The 
range limits are not enforced when MinValue and MaxValue have the same value, 
or when MaxValue is smaller than MinValue. When neither MinValue nor MaxValue 
have been assigned, either -Inf or +Inf is displayed as the value for the 
control. If either MinValue or MaxValue has been given an explicit 
non-default value, the Value property is updated with corresponding range 
limit.
</p>
<p>
In LCL version 3.0, the floating point property editor will not allow an 
invalid value to be stored in the Value property at design-time. An error is 
raised (and handled) with the message 'Property value out of range', and the 
Value property is not updated.
</p>
<p>
LCL versions prior to 3.0 allowed the values +Inf, -Inf, and NaN to be 
assigned as the property value. These values are no longer supported in LCL 
version 3.0 and later.
</p>
<p>
Use the MinValue and MaxValue properties to define the lower and upper limits 
for the Value in the control. Like Value, they are implemented as a Double 
type with the same range limits. An invalid value causes the property to be 
set to the corresponding range limit for the real type.
</p>
<p>
Use the DecimalPlaces property to specify the number of decimal digits 
displayed for a value not represented using the radix/precision/exponent 
format for the IEE 754 value.
</p>
<p>
Use the Increment property to set the value added to or subtracted from the 
control Value when the up or down buttons are clicked.

Changing the value for the property causes the <var>UpdateControl</var>

<element name="TFloatSpinEdit">
<short>
Implements a spin edit control using a floating point value.
</short>
<descr>
<p>
<var>TFloatSpinEdit</var> is a <var>TCustomFloatSpinEdit</var> descendant 
which implements a float-based spin edit control. It provides an edit control 
where the Float value can be entered directly, and up / down buttons which 
can be used to increment or decrement the <var>Value</var> for the control.
</p>
<p>
Use the Value property to assign a floating point value to the control as a 
Double type. Value is a 64-bit real type in the range 5.0E-324 .. 1.7E308 
(inclusive), and allows up to 15-16 digits of precision (15 digits for a 
negative value).
</p>
<p>
At run-time, setting Value to a number outside of the range for the real type 
causes Value to be updated. When neither MinValue nor MaxValue have been 
assigned, either -Inf or +Inf is displayed as the value for the control. If 
either MinValue or MaxValue has been given an explicit non-default value, the 
Value property is updated with corresponding range limit.
</p>
<p>
In LCL version 3.0, the floating point property editor will not allow an 
invalid value to be stored in the Value property at design-time. An error is 
raised (and handled) with the message 'Property value out of range'. The 
Value property is reset to 0.
</p>
<p>
LCL versions prior to 3.0 allowed the values +Inf, -Inf, and NaN to be 
assigned to the Value property. These values are no longer supported in LCL 
version 3.0 and later.
</p>
<p>
Use the MinValue and MaxValue properties to define the lower and upper limits 
for the Value in the control. Like Value, they are implemented as a Double 
type with the same range limits. An invalid value causes the property to be 
set to the corresponding range limit for the real type.
</p>
<p>
Use the DecimalPlaces property to specify the number of decimal digits 
displayed for a value not represented using the radix/precision/exponent 
format for the IEE 754 value.
</p>
<p>
Use the Increment property to set the value added to or subtracted from the 
control Value when the up or down buttons are clicked.
</p>
</descr>

<version>
Modified in LCL version 3.0 to implement range checking with floating point 
property editor support.

</element>

<element name="TFloatSpinEdit.AutoSelected">
<short>
Indicates whether the selected content in the control has been automatically 
selected.
</short>
<descr>
<p>
<var>AutoSelected</var> is updated in methods which handle focus change 
actions for the control, including: MouseDown, MouseUp, DoEnter, and DoExit. 
In general, it indicates when the Text and SelText properties have the same 
value.
</p>
<p>
The visibility for the property is public, and does not appear in the Object 
Inspector at design-time. It is, however, available in code at run-time. It 
is not declared as a read-only property, but there is no obvious reason to 
assign a value that does not result from calling the SelectAll method.
</p>
<p>
Use AutoSelect to control whether auto-selection is enabled for the control.

<var>OnChange</var> event is similar to <var>TCustomEdit.OnChange</var>, and 
is signalled for changes made by the user and for changes made in code. A 
change is a modification which will cause the text displayed on the screen by 
the control to be altered. This corresponds to a change in the Value property 
for the control. The event is called after the change takes place, so Value 
will already have the new property value.

<var>Value</var> contains the value for the spin edit control. Its content

up and down cursor keys, edit box for the control). It can also be directly 
assigned in program code.
</p>
<p>
Changing the value for the property causes the <var>Text</var> for the 
control to be checked for a valid numeric representation in the property. If 
the new property value is the same as the existing value, no actions are 
performed.
</p>
<p>
When the property value has been stored, internal flags are set to ensure 
that <var>Modified</var> is updated accordingly and the private 
<var>UpdateControl</var> method in the ancestor is called. If the handle for 
the control has been allocated, the <var>Change</var> method in the ancestor
