DESCRIPTION


COXBaseBrowseDirEdit is the template class derived from COXDropEdit, which in its
turn is the  template class that provides the functionality of adding dropdown button
to any edit control. Dropdown button is displayed on the right or left side of the 
edit box and takes all height of the control window. The width of the dropdown button 
can be set programmatically (by default we use the width of the current width of 
the scroll bar). 

COXBaseBrowseDirEdit class provides the implementation of the dropdown event that 
happens when the dropdown button is clicked. This includes displaying the Directory
Picker dialog that implemented using our COXFolderPickerDlg class. You can specify
the title of the Directory Picker dialog using the following function:

	SetBrowseDialogTitle();

To retrieve the title call the function:

	GetBrowseDialogTitle();

The directory that is picked in the Directory Picker dialog is saved and can be retrieved
or programmtically set using these functions:

	GetPath();
	SetPath();


As you can see COXBaseBrowseDirEdit is the template class that allows us to use
any edit control class as the base one. We provide our own COXBaseBrowseDirEdit
derivation that uses our COXEdit class as the base edit control class. The class
is named as COXBrowseDirEdit and declared as following:

	class OX_CLASS_DECL COXBrowseDirEdit : 
		public COXBaseBrowseDirEdit<COXEdit> {};

We chose COXEdit as the base because it provides a lot of functionality that
might be extremely useful (e.g. text and background color, mask).


Also we've desined and implemented the following two template classes that are
derived from COXBaseBrowseDirEdit:

1)	COXBaseBrowseDirEdit16
	
	Provides the same functionality as COXBaseBrowseDirEdit, the only difference is 
	that it uses COXDirectoryDialog class to display the Directory Picker dialog. 

	We provide our own COXBaseBrowseDirEdit16 derivation that uses our COXEdit 
	class as the base edit control class. The class is named as COXBrowseDirEdit16 
	and declared as following:

	class OX_CLASS_DECL COXBrowseDirEdit16 : 
		public COXBaseBrowseDirEdit16<COXEdit> {};


2)	COXBaseBrowseFileEdit

	Provides the same functionality as COXBaseBrowseDirEdit, the only difference is 
	that it uses standard CFileDialog class to display the File Picker dialog. 
	The pointer to the dialog can be retrieved using the following function:

	inline CFileDialog* GetFileDialog() { return &m_fileDlg; }

	We provide our own COXBaseBrowseFileEdit derivation that uses our COXEdit 
	class as the base edit control class. The class is named as COXBrowseFileEdit 
	and declared as following:

	class OX_CLASS_DECL COXBaseBrowseFileEdit : 
		public COXBrowseFileEdit<COXEdit> {};


  


Take a look at the ExtendedEditControls sample that can be found in the 
.\Samples\gui\ExtendedEditControls subdirectory of your Ultimate Toolbox directory.
In the sample check out the 'Drop Edit' page that demonstrate the use of 
COXBrowseDirEdit, COXBrowseDirEdit16 and COXBrowseFileEdit classes.
