Why does not work this simple code?

[trey]

Put on form

UniPanel1: TUniPanel;

UniButton1: TUniButton;

UniProgressBar1: TUniProgressBar;

UniLabel1: TUniLabel;

Run on WebBrowser

uses
 Windows, Messages, SysUtils, Variants, Classes, Graphics,
 Controls, Forms, Dialogs, uniGUITypes, uniGUIAbstractClasses,
 uniGUIClasses, uniGUIForm, uniLabel, uniProgressBar, uniButton,
 uniGUIBaseClasses, uniPanel;

type
 TMainForm = class(TUniForm)
   UniPanel1: TUniPanel;
   UniButton1: TUniButton;
   UniProgressBar1: TUniProgressBar;
   UniLabel1: TUniLabel;
   procedure UniFormCreate(Sender: TObject);
   procedure UniButton1Click(Sender: TObject);
 private
   { Private declarations }
 public
   { Public declarations }
 end;

function MainForm: TMainForm;

implementation

{$R *.dfm}

uses
 uniGUIVars, MainModule, ServerModule, uniGUIServer;

function MainForm: TMainForm;
begin
 Result := TMainForm(UniMainModule.GetFormInstance(TMainForm));
end;

procedure TMainForm.UniButton1Click(Sender: TObject);
var i:integer;
begin
UniProgressBar1.Max:=100; 
UniPanel1.Visible:=true;  // 1. why does not work?
for i:=0 to 100 do
 begin
   sleep(10);
   UniLabel1.Text:=inttostr(i); // 2. why does not work?
   UniProgressBar1.Position:=i; // 3. why does not work?
   Application.ProcessMessages; // 4. why does not work?
   UniProgressBar1.Refresh; // 5. why does not work?
   UniProgressBar1.RePaint; // 6. why does not work?
 end;
UniPanel1.Visible:=false; 
end;

procedure TMainForm.UniFormCreate(Sender: TObject);
begin
UniServerModule.MainFormDisplayMode:=mfPage;
UniPanel1.Visible:=false;
end;

initialization
 RegisterMainFormClass(TMainForm);

end.

 

 

I even tried to run the UniProgressBar1.Position in a new threads , but webform is dead when the cycle runs.

Thanks for the link. but!

Why should I write "bikes"?

why asynchronous operation can not be achieved by the component itself?

why methods Repaint, Refresh, in components when it does not work ?

Those methods were for desktop mode, not a web. you need to remember this is a framework for dual UI mode.

 

UniGUI is a fresh one, it's not a mature framework yet. This is its first step so you need to manage some action your-self.

 

By the way, your question is a good idea. By a "Asynchronous" nature it is possible that every UniGUI component's methods can parallel send and receive ajax-request itself, but that needs more design and take more time to implement. Implement more web UI supported by ExtJS should be the first priority, IMO.
