Re: [Gnoga-list] update images ?
You have to use an html trick. When specificity the image name each time add ?SomeValue. You can use a time stamp to make easy. The server will discard the ? and the rest of the URL but the browser will force a reload since it assume the image is dynamic now based in the query sent with image name.

Re: [Gnoga-list] updating html-tables without flickering ?
Double buffer. Create a second table that is hidden. Fill it in. Hide first
and show second. Can either delete the old one or recycle it.

[Gnoga-list] update images ?
Hi! I have a gnoga app that contains 2 images. They display nicely with View.Image_Holder.Create (View); View.Matched_Image.Create(View.Image_Holder, "https://path/matched.png";); View.Lapsed_Image.Create(View.Image_Holder, "https://path/settled_vs_lapsed.png";); where Image_Holder : Gnoga.Gui.Element.Common.DIV_Type; Lapsed_Image : Gnoga.Gui.Element.Common.IMG_Type; Matched_Image : Gnoga.Gui.Element.Common.IMG_Type; However, the server holding the images are creating new images every 10 minutes in a cron job. The images are diagrams, created with gnuplot, and published via https So, how can I make gnoga reload the images ? -- -- Björn -- Don't Limit Your Business. Reach for the Cloud.

[Gnoga-list] updating html-tables without flickering ?
Hi!
I got a page that is driven by a task that
updates 3 tables.
The tables are first set to "" with
View.Daily_Table.Inner_HTML ("");
then a header row is created
View.Daily_Table.Add_Caption("Last week's result @ " &
Calendar2.Clock.To_String(Milliseconds => False));
View.Daily_Table.Border;
declare
Row : Table_Row_Access := new Table_Row_Type;
Col1 : Table_Heading_Access := new Table_Heading_Type;
Col2 : Table_Heading_Access := new Table_Heading_Type;
Col3 : Table_Heading_Access := new Table_Heading_Type;
begin
Row.Dynamic;
Col1.Dynamic;
Col2.Dynamic;
Col3.Dynamic;
Row.Create (View.Daily_Table);
Col1.Create (Row.all, "Betname");
Col2.Create (Row.all, "Sum(Profit)");
Col3.Create (Row.all, "Date");
end;
and then the rows are added
Select_Daily_Profit.Open_Cursor;
loop
Select_Daily_Profit.Fetch(Eos);
exit when Eos;
Select_Daily_Profit.Get("BETNAME", Betname);
Select_Daily_Profit.Get("SUMPROFIT", Sumprofit);
Select_Daily_Profit.Get_Date("DATE", Date);
declare
Row : Table_Row_Access := new Table_Row_Type;
Col1 : Table_Column_Access := new Table_Column_Type;
Col2 : Table_Column_Access := new Table_Column_Type;
Col3 : Table_Column_Access := new Table_Column_Type;
begin
Cnt := Cnt +1;
Row.Dynamic;
Col1.Dynamic;
Col2.Dynamic;
Col3.Dynamic;
Row.Create (View.Daily_Table);
if Cnt mod 2 = Integer_4(0) then
Row.Background_Color("skyblue");
end if;
Col1.Create (Row.all, Utils.Trim(Betname));
Col2.Create (Row.all, Utils.F8_Image(Sumprofit));
if Sumprofit < 0.0 then
Col2.Background_Color("red");
else
Col2.Background_Color("palegreen");
end if;
Col3.Create (Row.all, Date.String_Date_ISO);
Col2.Text_Alignment(Gnoga.Gui.Element.Right);
end;
end loop;
Select_Daily_Profit.Close_Cursor;
This pattern is repeated for 3 tables with different data.
Now - it works.
But you see the tables disappear and the reappear, somewhat slowly.
And it's a bit annoying, since it is a monitoring screen.
I'd like the update to be without flickering. Is there a better way of
updating tables?
