Subject:  [VOICENWS] General: DevCon: new File Open Dialog - update your applications

++ From the VOICE OS/2-eCS News Service   http://www.os2voice.org ++ 

From: eugenegorbunoffDESPAM at DESPAMmail.ru

=== New PM controls for developers of applications ===  

 * New library includes: WC_DIRTREE and WC_FILEVIEW. This PM-controls may be used in applications to select directory and/or file. All heavy operations are performed in separate threads. Call FOCInitialize() before usage of the controls.  

* The control elements notify owner about state changes via WM_CONTROL message.  

* The elements support d\'n\'d operation (as source).  

* You can force change of directory, create/remove directories, rename files and directories using special messages. Moreover, the developers of applications can send messages to sort the contents of container, request list of selected files and directories.  

* Both control elements can work in conjuction: the changes in directory tree influence on container with files and vice versa.

=== Replacement of System File Open Dialog ===  

 

(under construction)  

 

* The main goal of the project - replace system file open dialog with new one based on new PM controls.   

* New dialog may be resized, users can change sorting, size of sub-windows. All parameters are saved and restored automatically.  

* New dialog is fully compatible with old system dialog: if you are going call new FOC then use FOCFILEDLG structure (instead of FILEDLG), instead of functions WinFileDlg, WinDefFileDlgProc, WinFreeFileDlgList  use: FOCFileDlg, FOCDefFileDlgProc and FOCFreeFileDlgList   

 

=== Dialog for directory selection ===  

 

* New dialog is based on WC_DIRTEE control. The interface is similar to the interface of FOC, API: FOCSelectDir, FOCDefSelectDirProc and FOCSELDIR structure.

 === Current plan of work ===  

 * create WC_PREVIEW control, include it to file open dialog.  

* full support of d\'n\'d.  

* we should update external view one more time.  

 

 === Join testing ===

 Let\'s test:  

* compatibility with different file systems  

* browse directories with huge quantity of files
