<var>EditMask</var> is a <var>String</var> property which contains the mask specification for the edit control. EditMask contains the delimited mask fields with the character types, storage specifier, and the character used to represent a space in the edit mask. For example:
</p>
<code>AMaskEdit.EditMask := '999.999;1;0';</code>
<p>
The EditMask is formed with a pattern of characters with the following meaning:
</p>
<table>
<tr>
<td><b>\ </b></td>
<td>after this you can set an arbitrary char</td>
</tr>
<tr>
<td><b>&gt; </b></td>
<td>after this the chars is in upper case</td>
</tr>
<tr>
<td><b>&lt; </b></td>
<td>after this the chars is in lower case</td>
</tr>
<tr>
<td><b>l </b></td>
<td>only a letter but not necessary</td>
</tr>
<tr>
<td><b>L </b></td>
<td>only a letter</td>
</tr>
<tr>
<td><b>a </b></td>
<td>an alphanumeric char (['A'..'Z','a..'z','0'..'9']) but not necessary</td>
</tr>
<tr>
<td><b>A </b></td>
<td>an alphanumeric char</td>
</tr>
<tr>
<td><b>c </b></td>
<td>any Utf8 char but not necessary</td>
</tr>
<tr>
<td><b>C </b></td>
<td>any Utf8 char #32 - #255</td>
</tr>
<tr>
<td><b>9 </b></td>
<td>only a number but not necessary</td>
</tr>
<tr>
<td><b>0 </b></td>
<td>only a number</td>
</tr>
<tr>
<td><b># </b></td>
<td>only a number or + or -, but not necessary</td>
</tr>
<tr>
<td><b>: </b></td>
<td>automatically put the hour separator char</td>
</tr>
<tr>
<td><b>/ </b></td>
<td>automatically put the date separator char</td>
</tr>
<tr>
<td><b>h </b></td>
<td>a hexadecimal character but not necessary (Lazarus extension, not supported by Delphi)</td>
</tr>
<tr>
<td><b>H </b></td>
<td>a hexadecimal character (Lazarus extension, not supported by Delphi)</td>
</tr>
<tr>
<td><b>b </b></td>
<td>a binary character but not necessary (Lazarus extension, not supported by Delphi)</td>
</tr>
<tr>
<td><b>B </b></td>
<td>a binary character (Lazarus extension, not supported by Delphi)</td>
</tr>
<tr>
<td><b>! </b></td>
<td>Trim leading blanks, otherwise trim trailing blanks from the data</td>
</tr>

<p>
Setting a new value for the property causes the value to be decomposed into the internal <var>TInternalMask</var> representing the individual characters in the edit mask. Individual UTF-8 characters in <var>Value</var> are either added to the mask as literals or character types. <var>Clear</var> is called to remove the displayed value in the control, and the initial <var>Text</var> value is set to the value from <var>RealGetText</var>.
