[Sebaot Web]

Delphi supports calling REST services for example. Node.js has plenty of libraries to implement REST server. So create a REST web service in node and use it from Delphi. Or vice versa. UniGUI is kind of irrelevant here.

Node.js is just an executable running on server, not any different to php for example. Choose the exchanging interface and format (REST, XML, plan json, your own custom one) and implement it in both unigui and node to communicate.

[SessionTimeOut]

Is there any way to optionally disable logging of EUniSessionException session timeout messages? More than 90% of logged events are them in my apps logs.

[Hotkey to shutdown when debugging]

I can just press Ctrl+F2 for that. But I don't want to kill the process. I want unigui to shutdown normally, write proper log messages including my own ones, call all relevant events inside the app and don't pile up icons of killed processes in system tray.

[Hotkey to shutdown when debugging]

Is it possible to add a shortcut property like ServerModule.DebugShutdownKey, so when DebugHook <> 0 and the keys are pressed, unigui will shutdown itself?

I run unigui dozens of times per day, and every time need to select with mouse a tray icon, right click for popup menu, then click Shutdown. Quite annoying really when you do that again and again, day after day.

[Лицензионный uniGUI]

Купил, работает как часы. Уже больше 3 лет использую без нареканий под IIS.

В унигуи, на мой взгляд, только одна проблема - высокие требования к качеству связи. Если в сети идет потеря пакетов, то при работе в унигуи программа будет часто вылетать по "session timeout", и пользователю придется входить заново.

[Closing application]

Is there a proper way to close application if I have a "Quit" button?

- calling Close on MainForm

- MainModule.UniMainModule.Terminate

- anything else?

[Switch off unused events]

Greetings!

 

All my uni apps work in mfPage, insert frames and rarely open a single form with ShowModal for some user input, and I don't care where user can drag that window. But unigui still generates ajax events for all actions even if they are not needed for app to function properly.

So is it possible to create some EventOptions in ServerModule where selected event types can be swiched off to speed up? I'm sure there are other non essential events out there besides form's position that are not required by every application.

For another example I don't need real position and size of controls on my forms and frames if user resizes browser window since browser alings everything itself, so would like to disable all such events too.

What I try to achieve is smooth appearance and work of full page apps like this one

while now you can notice huge delays in repainting.

[Checkbox in UniDBGrid]

Is it possible when UniColumn.CheckBoxField.Autopost = True to show DBGrid.LoaingMask if it is set? Posts can take time on large databases.

 

By the way, I get a typecast exception from unigui when UniColumn.CheckBoxField.BooleanFieldOnly = False and DisplayValues = '' if I want to show only checkboxes without any labels. Can be workarounded by using spaces DisplayValues = ' ; ' (happens with fmsoft_unigui_plus_pro_0.97.0.1085_beta)

 

[10 general design questions...]

For 10, I prefer to put the list grid and other controls on a panel. When showing detail frame I make this panel invisible and show detail on top of it, when closing detail frame I make list visible again. Less queries opened, reduced delay and immediate update of changed fields in the list (if using Post on the same dataset as in list). Good for mfPage full screen applications to use all the available browser space instead of messing with forms and their size.

[how to show uniscreenmask manually]

It won't work since you want to show a mask in the same server event with calling report generation. The easiest solution is to create your own dialog form with Yes and No buttons, and enable screen mask in Yes button properties.

[Set TUniDBGrid's Column Width with percentage]

It has already been posted several times how to autowidth columns, I made a helper function

procedure UniDBGridAutoWidth(aGrid: TUniDBGrid; aFieldName: string = '');
var
  s: string;
  i: Integer;
begin
  if aFieldName = '' then
    s := 'sender.headerCt.forceFit=true;'
  else with TStringList.Create do try
    Delimiter := ';';
    StrictDelimiter := True;
    DelimitedText := LowerCase(aFieldName);
    for i := 0 to Pred(aGrid.Columns.Count) do
      if IndexOf(LowerCase(aGrid.Columns[i].FieldName)) <> -1 then
        s := s + Format('columns[%d].flex=1;', [i]);
  finally
    Free;
  end;

  if s <> '' then
    aGrid.ClientEvents.ExtEvents.Add(Format(
      'beforereconfigure=function beforereconfigure(sender, store, columns, oldStore, the, eOpts)' +
      '{%s}', [s])
    );
end;

Pass a field name to autowidth, or several field names separated with ';'.

If you don't pass any fields, all of them will have autowidth relating to their width set in designer.

[Collapsible grid]

I can't set DBGrid.Grouping.Collapsible to True in the latest 1085 build, and if I try to collapse grid using this js code

    UniSession.AddJS(DBGrid1.JSName + '.view.features[0].collapseAll();')

it causes visual glitches (repeatable '+' signs) in group's headers. Did I miss something?

However when I test myself it always works in IE11 which I have. So the issue is hard to reproduce, but it is definitely there.

Nope.

You put it in CalcFields event of DataSet.

[UniDBGrid Picture from URL]

however

given that the URL is only a string, how do I tell it to display (fetch the image) instead of displaying a string?

Create calculated widestring field, and use html tags

DataSet.FieldByName('calc_youtube').AsString := Format('<img src="%s">', [DataSet.FieldByName('youtube_url').AsString]);
