<element name="TFileAttr">
<short>
Enumerated type with file and directory attributes used in TFileListBox.
</short>
<descr>
<p>
<var>TFileAttr</var> is an enumerated type with values that represent file 
and directory attributes for a selection in <var>TFileListBox</var>. Values 
from TFileAttr are stored in the <var>TFileType</var> set, which is used to 
implement the <var>FileType</var> property in TFileListBox.
</p>
<p>
Values in TFileAttr generally correspond to the file attributes used in 
<var>TSearchRec</var> from the FreePascal RTL (Run-Time Library). The 
differences are:
</p>
<dl>
<dt>ftNormal</dt>
<dd>
This represents a file lacking any other file attributes; represented in 
TSearchRec with the Integer value <b>0</b> (<b>zero</b>).
</dd>
<dt>fsAnyFile</dt>
<dd>
This value from TSearchRec is not represented in TFileAttr; it is a search 
mask and not an actual file attribute.

<element name="TCustomFileListBox">
<short>Implements the base class for a file selection list box.</short>
<descr>
<p>
<var>TCustomFileListBox</var> is a TCustomListBox descendant which implements 
the base type for <var>TFileListBox</var>. TCustomFileListBox extends the 
ancestor with properties, methods, and events used to select a file or 
directory on the local file system in a list box control.
</p>
<p>
Use the <var>Drive</var> and <var>Directory</var> properties to specify the 
location on the local file system displayed in the list box. Please note that 
Drive is not used on UNIX-like file systems.
</p>
<p>
Use <var>FileType</var> to specify the files and/or directories which can be 
displayed in the control.
</p>
<p>
Use <var>Mask</var> to specify a file mask (with optional wildcards) used to 
select the files displayed in the control. Please note that wild cards may be 
implemented differently for some file systems. For example: <b>'*'</b> is the 
"all files" mask on UNIX-like file systems instead of <b>"*.*"</b>.
</p>
<p>
Use the <var>Sorted</var> property to control the order of files and 
directories displayed in the control.
</p>
<p>
Use <var>Items</var> to access the file and/or directory names matching the 
FileType and Mask in the current Directory for the control. Directory names 
are enclosed in square brackets (<b>[]</b>).
</p>
<p>
Use <var>FileName</var> or <var>ItemIndex</var> to get or set the current 
selection in the control.
</p>
<p>
Assign an object procedure to the <var>OnChange</var> event handler to 
perform actions needed when a new item has been selected in the control.
</p>
<p>
Do not create instances of <var>TCustomFileListBox</var>. Use the 
<var>TFileListBox</var> descendant which sets the visibility of properties 
used in the class instance.

<element name="TCustomFileListBox.UpdateFileList">
<short>
Loads the list of files and/or directories for the list box control.
</short>
<descr>
<p>
<var>UpdateFileList</var> is a method used to load the list of file and/or 
directory names in the Items for the control. No actions are performed in the 
method at design-time, or when the component is being loaded using the LCL 
streaming mechanism.
</p>
<p>
UpdateFileList calls <var>Clear</var> to remove any existing values in the 
<var>Items</var> property.
</p>
<p>
Values in <var>FileType</var> are used to construct file attributes needed 
for use with <var>TSearchRec</var>. The <var>FindFirstUTF8</var> and 
<var>FindNextUTF8</var> routines from <file>LazFileUtils</file> are used to 
find matching file or directory names in the <var>Directory</var> for the 
control. Each value returned for the TSearchRec is compared to the 
<var>Mask</var> and <var>FileType</var> defined in the control. Acceptable 
values are added to the <var>Items</var> property.
</p>
<p>
Please note that Directory names (included when FileType contains 
ftDirectory) are surrounded by <b>square brackets</b> (<b>'[]'</b>) when 
added to the Items property.
</p>
<p>
The private <var>UpdateSelectedFileName</var> method is called to include 
path information in <var>FileName</var> for the selected item in the control.
</p>
<p>
UpdateFileList is called in the implementation of the <var>Create</var> and 
<var>Loaded</var> methods. It is also called when a new value is assigned to 
<var>Drive</var>, <var>Directory</var>, <var>FileType</var>, or 
<var>Mask</var>.
</p>
</descr>
<seealso/>
</element>

<element name="TCustomFileListBox.Drive">
<short>
The <var>Drive</var> on which the file is located (applies to Windows 
systems).
</short>
<descr>
<p>
<var>Drive</var> is a Char property which indicates the current drive letter 
for the Directory in the list box control. Drive is relevant for file systems 
which use drive designations (Windows).
</p>
<p>
The default value for the property is <b>' '</b> (space character). Changing 
the value in Drive causes the UpdateFileList method to be called to fill the 
list of Items displayed in the list box control.
</p>
<p>
Use Directory to specify the path on the local file system to the entries 
displayed in the control.
</p>
<remark>
Setting a new value in Drive does not automatically alter the value in 
Directory. Always assign an explicit value to Directory when setting the 
value in Drive. In addition, setting a value in Directory which includes a 
drive designator like 'd:\config\' does not update the value in Drive. The 
only time Drive is automatically sync'd to the value in Directory is in the 
Create constructor.

<element name="TCustomFileListBox.Directory">
<short>
The <var>Directory</var> or Folder in which the file is located.
</short>
<descr>
<p>
<var>Directory</var> is a <var>String</var> property which contains the path 
on the local file system to the files or and/or directories displayed in the 
list box control. The initial value for Directory is assigned in the 
constructor and defaults to the current directory for the application.
</p>
<p>
The value in Directory is prepended to the value in <var>Filename</var> when 
the <var>UpdateSelectedFileName</var> method is called from methods like: 
<var>Click</var>, <var>KeyUp</var>, <var>SetItemIndex</var>, 
<var>SetFileName</var>.
</p>
<p>
Changing the value in Directory causes the <var>UpdateFileList</var> method 
to be called to reload the file and or directory names stored in the 
<var>Items</var> property.
</p>
<remark>
Changing the value in Directory does not automatically update the value in 
Drive. If Directory includes a drive designator like 'D:\config\', the drive 
portion is not applied to the Drive property. In addition, setting a value in 
Drive does not update the value in Directory. The only time Drive and 
Directory are automatically sync'd is in the Create constructor.

<var>FileName</var> is a <var>String</var> property which contains the file 
name for the currently selected item in the list box control. The value in 
FileName is updated when an item in the control is selected, or when a new 
value is assigned to the <var>ItemIndex</var> property.
</p>
<p>
Assigning a new value to the property causes the <var>IndexOfFile</var> 
method to be called to locate the specified value in the <var>Items</var> for 
the control. The private <var>UpdateSelectedFileName</var> method is called 
to ensure that the new file name includes the path information in

<p>
<var>FileType</var> is a <var>TFileType</var> set property which contains 
zero (0) or more values from the <var>TFileAttr</var> enumeration. FileType 
determines the file system entries displayed in the list box control. See 
<link id="TFileAttr">TFileAttr</link> for more information about the 
enumeration values and their meanings.
</p>
<p>
The default value for the property is <b>[ftNormal]</b>.

<short>Contains the mask for files selected for the control.</short>
<descr>
<p>
<var>Mask</var> should be filled with one or more file masks separated by 
semi-colons. For example: <b>'*.pdf;*.svg'</b> will show all files with the 
extensions pdf and svg. The default value for the property is <b>'*'</b> 
which is the generic mask meaning any file or directory. Do not use the 
Windows specific mask <b>'*.*'</b> to attempt to show all files, which is the 
behavior from Delphi. In the LCL version of the control '*.*' will 
<b>require</b> the file name to have an extension.
</p>
<p>
Allowed wildcards include <b>'*.*'</b> which means zero or more characters, 
and <b>'?'</b> which means exactly 1 character with any value. Other 
characters represent themselves with one important detail: The file matching 
algorithm is <b>not</b> case sensitive. So if you set '*.PDF' in the mask, 
then 'PostScript.pdf' will also be shown, even on Linux which is a case 
sensitive file system.
</p>
<p>
This property has exactly the same rules and behavior as the <var>Mask</var> 
property in <var>TFilterComboBox</var>.
</p>

a value directly to the <var>FileName</var> property, and when the list of 
file system entries in the control is reloaded.

<descr>
<p>
<var>TCustomFilterComboBox</var> is a <var>TCustomComboBox</var> descendant 
which defines a combo-box used to select files which match a selection filter.
</p>
<p>
Use the <var>Filter</var> property to define the filter names and expressions 
available in the drop-down for the combo-box. Only the filter name is 
displayed in the combo-box.
</p>
<p>
Use <var>AutoComplete</var> to enable or disable case-insensitive automatic 
text completion in the edit area for the combo-box. When set to <b>True</b>, 
the Filter which starts the the typed value is located and selected in the 
control. Please note that AutoComplete works when the text area is empty, or 
when the entire contents of the editable are are selected.
</p>
<p>
Use <var>ItemIndex</var> to get the ordinal position in Filter for the 
selected filter. Use the <var>OnSelect</var> event handler to perform actions 
needed when a new value is selected in the combo-box.
</p>
<p>
TCustomFilterComboBox includes a <var>ShellListView</var> property with the 
<var>TShellListView</var> instance used to display the list of files matching 
the selected filter. ShellListView is updated  (when assigned) in the 
<var>Select</var> method to use the value in <var>Mask</var> in the list view 
control. Set the <var>Root</var> property in ShellListView to control the 
directory displayed in the control.
</p>
<p>
TCustomFilterComboBox sets the visibility for properties defined in an 
ancestor class, and does not introduce any new properties, methods, or 
events. Please note that some properties are not published for the control, 
so do they do not appear in the Object Inspector at design-time. For example: 
Mask.
