DevCon: new File Open Dialog - update your applications

April 01, 2010 by eugenegorbunoff@mail.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.

 * 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 ===

* compatibility with different file systems


* browse directories with huge quantity of files
