[TThread in UNIGUI service. The service can't be stopped.]

On 6/1/2021 at 6:46 PM, Mehmet Emin said:

Since you are using CreateAnonymousThread and calling TUniServerModule.myproc, TUniServerModule has already same named property "Terminated". So I think you would better have your thread class and check the threads "Terminated" property within. Then you be able to exit the while loop. Also after FmyThread.Terminate; you can call thread waitfor better cleanup.

Got it, thanks !

[TThread in UNIGUI service. The service can't be stopped.]

I have first created my application as standalone project.

Now i have created the service application project.

The service start and works fine but when i try to stop it, it doesn't respond and can't be stopped.

The problem seems related to a thread that is created in the servermodule. If i remove this thread, the service can be stopped with no problem.

 

Probably i'm not doing it correcty. I'm going to describe how it work:

 

In the server module oncreate event i have used a code like this:

  FmyThread:=Tthread.CreateAnonymousThread(myproc);
  FmyThread.Start;

  FmyThread is defined in the private section of the server module.

 

In the server module onbeforeshutdown event i have placed code to terminate the thread

  FmyThread.Terminate;

 

The myproc procedure is like this

procedure TUniServerModule.myproc;
var
  Start,Finish:Tdatetime;
const
  SecBetweenRuns = 60;
begin
  Start:=now;
  while not Terminated do
  begin
    Finish:=now;
    if SecondsBetween(Start,Finish)>SecBetweenRuns then
    begin
       // Do something, the code execution is fast

      start:=Finish;
    end;

    sleep(1000);
  end;
end;

[ProcessEventQueue(): Worker is not assigned]

Ok i have the solution. See below. Let me know if there's another (better/faster) solution.

In the button have defined the JS event click (in Extevents)

 

function click(sender, e, eOpts)
{
  if (confirm("Confermation request")==true)
    ajaxRequest(sender, '_doit', []);  
}

 

in the button have definied the onajaxevent event

 

  if EventName = '_doit' then
  begin
    modalresult:=mrOk;
  end;

Ok, only now i have realized that there's a showmask property in the Tunibutton

It works fine BUT, if in the button onclick event a messagedlg method is executed, the mask is not visualized. Is it WAD ?

thanks

I was folgorated by an idea. Maybe I have to make the request for confirmation with JS code ? If this is correct could anyone tell me how? Unfortunately my knowledge of JS is zero.

Hello,

Here is a similar topic (in Russian).

Great! It works correctly!

Thanks a lot!

[unnimDBGrid-sliderbar]

Hayri, 

I'm sorry, but it isn't the correct solution for me.

I need the same visualization (that is, multiple pages if records are more than x), but without slidebar.

After that, I add 4 buttons (next, previous,first,last page) for move between pages (to replace the slidebar)

Hi,

I use mobile version.

I need to hide the bar for the change page. I need to insert four buttons: next, previous, first e last page

Thanks.

Ok, thanks.

BUT  if in the button that close the form i want a confirmation (see below), again there's the same problem. Is there a workaround for this ?

 

 

  if messagedlg('Confirm ?',mtConfirmation,[mbyes,mbno])=mrYes then
  begin
    ShowMask('Please wait ...');

    UniSession.Synchronize;

    modalresult:=mrOk;
  end;

This error shows that Synchronize() can not be called here for different reasons.

You should not use Synchronize to display masks. Simply enable ScreenMask property of the Button which closes the form.

 

Ok, thanks.

Roberto

[ProcessEventQueue(): Worker is not assigned]

I have the exception "ProcessEventQueue(): Worker is not assigned." when the statement "UniSession.Synchronize" is executed in the code below.

Is my code wrong ?

thanks

[TunnimDBgrid double click cell]

Mehmet,

your solution work! thanks a lot!

My implementation:

Quote

private 

var columnIDX,recordIDX:integer;

tunidbgrid->clientevents->extevents->childdoubletap

function childdoubletap(sender, location, eOpts)
{ 
  ajaxRequest(sender,'_doubleclick',["colidx=" +location.columnIndex, "rowidx="+location.recordindex]);
}

tunidbgrid->events->onAjaxEvent

  if EventName = '_doubleclick' then
  begin     
     columnIDX:= Params['colidx'].AsInteger;

      recordIDX:= Params['rowidx'].AsInteger;

  end;

tunidbgrid->events->ondblclick

   if columnIDX=0 then

   begin

       //do something

   end;

 

 

 

 

[TunnimDBgrid double click cell]

Mehmet, I'll try your solution and I hope to resolve the problem.

Thanks.

[TunnimDBgrid double click cell]

I've already seen that topic and it would be perfect, but... in my event list there isn't "itemtap".

 

[TunnimDBgrid double click cell]

Hi, 

I need  help.

I have a TunimDBgrid (for mobile). I would like to open a new form if i make a double click in a specific cell.

How i can impliment grid.dblclick? How i can get the colomn.index or name?

Thanks.

[Wrong tab sequence]

Regarding this problem i have created a support ticket but maybe somone else here can have a solution to the problem.

It happens that the tab stop sequence is not correct when cycling with TAB (and SHIRT-TAB) between components. My application is made of a main form and frames, that opened inside the main form.

I have attached to this message a self explained example that shows the problem.

thanks

[TuniDBGrid: select rows by code with a condition]

What i need is to select the rows of a grid depending on some condition. The condition in this particular case is the value of a field; if the field has some value the record must be selected, otherwise not selected. This task must be executed after the grid has been loaded so i guess the right place where to place the code is in the OnAfterLoad event of the grid.

Now i have the code to select or deselect all the rows but i have no idea how to select/unselect rows with a condition.

Possible ?

thanks

Please try below code

This works fine, thanks

[uniDBGrid1 - select all - with checkboxes]

On 10/30/2018 at 1:48 PM, Sherzod said:

Maybe you should try this approach for now:

1.

  
  YourGrid.JSInterface.JSAssign('needToSelectAll', [True]); //<---------
  liste.SQL.Clear;
  liste.SQL.Append('SELECT * FROM ANTEILE WHERE GUNST_INR  = '+STRUKTUR1.FieldByName('INR').asstring+' ORDER BY VERTRAG_NR desc ');
  liste.Open;

2.

YourGrid -> ClientEvents -> ExtEvents -> function store.load // or use the OnAfterLoad event of your Grid with some conditions

function store.load(sender, records, successful, operation, eOpts)
{
    if (sender.grid.needToSelectAll) {
        Ext.defer(function () {
            sender.grid.getSelectionModel().selectAll()
        }, 100);
    }
}

 

I'm trying this thing but sincerly i don't understand in what ext event i have to place the store.load function.

I'm new to JS and UNIGUI

I have tryed also to place the code UniSession.AddJS(UniDBGrid1.JSName + '.getSelectionModel().selectAll();'); in the onafterload event of the grid but it has no effect. If i use the same code in a popup menu works fine.

thanks

[Setting focused control in a Tuniframe]

My unigui application creates Tuniframe inside Tunitabsheet

At the end of the process the INIT method is executed.

The INIT method defined into the frame should move the focus to the desired component (setfocus). Anyway it doesn't work. this focus is somewhere (don't know where) and not in the correct component. I'm doing something wrong ?

thanks  

 

var
  ts:TUniTabSheet;
  idx: Integer;
  frame:Tstandard_frame;
begin
  ts:=TUniTabSheet.Create(self);
  ts.Closable:=true;

  frame:=Taframe.Create(ts);
 

  frame.Parent:=ts;
  frame.Align:=alClient;
  frame.Show;

  pc.ActivePageIndex:=ts.PageIndex;

  frame.Init; // THIS METHOD SHOULD MOVE THE FOCUS EXECUTING THE SETFOCUS METHOD OF THE DESIRED CONTROL (SEE BELOW)
end;

.......

procedure Taframe.init;override;
