    VCL Application + uniGUI Web Server

    in General

    Posted

    Hi.

    I read in uniGUI.pdf:

    2.1.3 VCL Application
    One of the unique features of uniGUI is its ability to create VCL applications which are a web server
    at the same time. This means that each VCL Application created with uniGUI library contains a Web
    Server.

     

    1. How add in VCL Application  uniGUI Web Server?

    Maybe this documentation is outdated?

     

    2. Is it possible to convert VCL Application in uniGUI?

     

    Thanks.

     

     

     

     

     

     

    Pressing TAB

    Posted

    Hi.

    On Form:

    UniEdit1 TabOrder=1

    UniEdit2 TabOrder=2 //OK focus

    UniEdit3 TabOrder=3 //OK focus

    UniBitBtn TabOrder=4 //I can not set the focus by pressing TAB

     

    I show this Form ShowModal()

    In event UniFormShow code UniEdit1->SetFocus();

    Then I press key TAB 3 times.

    Button does not want to receive focus. How correctly?

    Thanks.

    Hi.
    How I can change icon server?
    I try Project -> Options -> Application -> Load Icon
    but icon not change in tray. Maybe it because I use trial edition?
    Can I translate into another language server pop up menu (Restore/Shutdown)?
    This is not very important but I am wondering.
    Thanks.

    Hi,

     

    Try:

    UniChart1 -> ClientEvents -> UniEvents -> [Ext.chart.Chart [chart]] add function chart.beforeInit

    function chart.beforeInit(sender, config)
{
  sender.themeAttrs.seriesThemes = [{fill: '#ff4565'}, {fill: 'green'}, {fill: 'yellow'}];
  sender.themeAttrs.colors = ['#ff4565', 'green', 'yellow']
}

    Best regards.

    in General

    Posted

    Hi.

    I have one series.

    1.How I can change the color of this series?

    2.Can I change the color at the points of the series?
    For example temperature series. If the temperature is above 50 degrees is the point of the red, the other green. Is it possible?

    Thank you.

    Where more correct to open a database connection?

    In UniGUIMainModuleCreate or in UniFormShow?

    Thanks.

    //in UniMainModule
void __fastcall TUniMainModule::UniGUIMainModuleCreate(TObject *Sender)
{
 //FireDAC
 FDQuery1->Active = true;
 FDQuery1->FetchAll();
 FDQuery1->First();
}

//then in main form
void __fastcall TMainForm::UniFormShow(TObject *Sender)
{
 if(UniMainModule()->FDQuery1->RecordCount == 0)
 {
  ShowMessage(L"No data");
  return;
 }

 UniMainModule()->ClientDataSet1->Active = true;
}

//*************************************************

//Or all code in main form
void __fastcall TMainForm::UniFormShow(TObject *Sender)
{
 //FireDAC
 UniMainModule()->FDQuery1->Active = true;
 UniMainModule()->FDQuery1->FetchAll();
 UniMainModule()->FDQuery1->First();
 if(UniMainModule()->FDQuery1->RecordCount == 0)
 {
  ShowMessage(L"No data");
  return;
 }

 UniMainModule()->ClientDataSet1->Active = true;
}
