Introducing TMS FNC AppTools

Thursday, March 17, 2022

We are proud to announce a new member of the TMS FNC family: TMS FNC AppTools!

What is TMS FNC AppTools?

Compared to the rest of the FNC family (that is the family of our universal components), TMS FNC AppTools is a little bit different. It revolves exclusively around desktop application development! The reason for this is simple: desktop and mobile applications are unalike and some functionalities/features make no sense or restricted in mobile environments. This way we can fully focus on desktop specific needs.

What is included?

Let's take a look at what is included in this first release!

TTMSFNCAppUpdate

Manage automatic internet based application updates. You can use HTTPS based locations for secure downloads. Username and password protected downloads are also supported!

The entry point to the automatic update is an .INF control file. By calling TTMSFNCAppUpdate.NewVersionAvailable the component will download and look at the contents of the control file. A single control file can be used to handle the updates for 3 supported platforms at the same time. This is achieved by a platform suffix (= win, macos or linux):

[update_platform]
keywords

[files_platform]
count=N

[file1_platform]
keywords

…

[fileN_platform]
keywords

The TTMSFNCAppUpdate component will automatically scan the control file for the platform it is running on, which means the platform specific suffix is always needed.

TTMSFNCAppUpdate gives huge flexibility after the control file has been read. When NewVersionAvailable is called, the FileList collection property will be filled with the contents of the control file. This allows you to freely remove or modify the file descriptors before continuing with the update.

procedure TForm1.Button1Click(Sender: TObject);
begin
  if TMSFNCAppUpdate1.NewVersionAvailable then
  begin
    if TMSFNCAppUpdate1.FileList.Count > 0 then
      TMSFNCAppUpdate1.FileList[0].URL := 'newdownloadurl';

    TMSFNCAppUpdate1.StartUpdate;
  end;
end;

This becomes a lot simpler if you don't need to change the file descriptors afterwards. Just call DoUpdate which will internally use NewVersionAvailable and StartUpdate and run the whole process at once.

TTMSFNCAppUpdate also supports predefined and custom prefixes that will be replaced in the path related keywords. For example: {APP} stands for the application folder. For custom prefixes you can implement the OnCustomPrefix event!

Curious to see it in action? Check our first video we prepared:

TTMSFNCAppFormPersist

With this component you can automatically persist and restore your application windows' position, this way the application will open all its windows where you left them.

It's also possible to save and load the position programmatically:

procedure TForm1.restoreBtnClick(Sender: TObject);
var
  afp: TTMSFNCAppFormPersist;
begin
  afp := TTMSFNCAppFormPersist.Create(Self);
  afp.FileName := './temp_settings.ini';
  afp.LoadFormSettings;
  afp.Free;
end;

procedure TForm1.saveBtnClick(Sender: TObject);
var
  afp: TTMSFNCAppFormPersist;
begin
  afp := TTMSFNCAppFormPersist.Create(Self);
  afp.FileName := './temp_settings.ini';
  afp.SaveFormSettings;
  afp.Free;
end;

TTMSFNCAppLock

Keep your current workflow and sensitive data hidden by password locking your running application when needed or if it has been idling for a while. After locking all application windows become minimized and hidden.

To unlock, click the minimized application icon and use the default unlock dialog. Alternatively a custom unlocking mechanism can be used by implementing the OnQueryUnlock event. It's also possible to unlock the application automatically by calling the Unlock method.

procedure TForm1.Button1Click(Sender: TObject);
begin
  //Unlock automatically after 30 seconds
  Timer1.Interval := 30000;
  Timer1.Enabled := True;
  TMSFNCAppLock1.Lock;
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  Timer1.Enabled := False;
  TMSFNCAppLock1.Unlock;
end;

A new form of documentation

Taking a step in a new direction we decided to break an old habit. For TMS FNC AppTools we offer online documentation! Take advantage of the search function, copy code snippets by clicking a single button or jump around following the in-page links.

Did you know? To navigate to the component documentation right away, you can use the design-time context menu and choose the "Documentation" menu item!

Availability

TMS FNC AppTools is available as a standalone product and as expected, it is also part of TMS ALL-ACCESS and TMS FNC Component Studio.

What's next?

This was just the first chapter in a new book. Share your ideas what would you like to see as a universal cross-platform component for desktop oriented development!

Hi TMS Team,
I was waiting for this FNC equivalent of VCL TWebUpdate for quite some time.
Thank you very much for this.

Application level tools are indeed a new territory to explore to simplify cross-platform Desktop application development.
Well done !
