    how set datasource of tunidbgrid after dataset open

    in General

    Posted

    It takes a long time to open the query. I want to show a form with an empty grid, after running a query in the background (fdquery.ResourceOptions.CmdExecMode: = amAsync) I want to show data in the grid, so it can not be done in beforeOpen.

    The second reason is two different queries, with different columns that I want to show in the same grid.

    how set datasource of tunidbgrid after dataset open

    First situation:

    Unidbgrid.datasource = datasource1;

    datasource1.dataset = fdquery1;

    after fdquery1.open in unidbgrid I can see columns and rows with data.

    Second situation:

    unidbgrid.datasource = null;

    datasource1.dataset = fdquery1;

    fdquery1.open;

    In afteropen of fdquery1:

    unidbgrid.datasource = datasource1;

    In this situation I can't see columns and rows, unidbgrid is "empty" until browser resize, form resize or click on refresh button of unidbgrid.

    Calling unidbgrid.JSInterface.JSCall('view.refresh', []); in afteropen of fdquery works, but when I set fdquery.ResourceOptions.CmdExecMode := amAsync then exception "Attempt to access nil session reference" is raising.

    exception on UniDBGrid1.JSInterface.JSCall('view.refresh', []) when called in FDQuery1AfterOpen when fdquery ResourceOptions.CmdExecMode is set to amAsync

    Why UniDBGrid1.JSInterface.JSCall('view.refresh', []); causes exception "Attempt to access nil session reference"? Is this problem with thread synchronization?

    procedure TMainForm.FDQuery1AfterOpen(DataSet: TDataSet);
    begin
      DataSource1.DataSet := FDQuery1;
      UniDBGrid1.DataSource := DataSource1;
      UniDBGrid1.JSInterface.JSCall('view.refresh', []);
    end;

     

     

    TUniTreeMenu how change source menu in runtime or hide invisible menu items

    in General

    Posted

    Uni gui version 1.70.0.1485

    In my app I have two types of users. For one of them I want to hide couple of menuitems or set Tunitreemenu other source menu depending on user type, how to do this in runtime?

    I found this solution , but it causes errors like hiding frames that must be visible!

    with mainMenu do
      begin
        SourceMenu.Items[0].Visible := False;

        _llist := '';
        for I := 0 to SourceMenu.Items.Count-1 do
          if not SourceMenu.Items.Visible then
            if _llist='' then _llist := '"'+SourceMenu.Items.Caption+'"'
            else _llist := _llist + ',"' + SourceMenu.Items.Caption+'"';

        if _llist<>'' then
        begin
          JSInterface.JSCall('getStore().clearFilter', []);
          JSInterface.JSCode(#1'.getStore().filterBy(function (record){ if (['+ _llist +'].indexOf(record.get("text"))>-1) return false; else return true;});');
        end
        else
          JSInterface.JSCall('getStore().clearFilter', []);
      end;

    Is it possible to set TUniToolButton on hover background to single color? Normally when mouse cursor is over toolbar button its background is painted with gradient, also toolbar is painted with gradient, but after set its color property it is painted with single color. I want to do the same thing with toolbar buttons backround when mouse is over button.

    UniDBGrid - how set const column width when grid have region center and 100% width and 100% height

    in General

    Posted

    Frame with uniAlignmentClient, layout border.

    UniDBGrid is placed on this frame with region center, width and height 100%. UniDBGrid have 2 columns, with width 60. When viewed in the browser, the columns occupy 100% of the width of the grid (its much more than 2x60). I would like the grid to fill the frame, but the columns have a fixed width.

    Also when browser is resizing, columns width are resizing. I would like the width of the columns not to change, only that the scrollbar appears.

    Communication with external REST

    in General

    Posted

    I want to communicate with external REST to synchronize (bidirectional) data between UniGUI App database and windows apps database. REST is directly connected with windows app database. In UniGUI app i will make a form with button, on button click I will call REST and save readed data to database. It is possible to fire this action without entering webbrowser and manually click button? For example via URL? This would help to make data synchronization automatic.

     

    Mayby someone can propose other way to do this?
