    uniGUI Beta "beforerender"

    in General

    Posted

    Hello, I'm starting beta testing to contribute to the tests and compiling my project in the latest version.
     
    Whenever I try to use the code below in the beta version "1.0.2.1442" my project gets white screen and no error is returned in the logs.
    But in that stable version "1.0.0.1425" is working perfectly.
    ClientEvents.ExtEvents.add('beforerender=function beforerender(sender, eOpts) { sender.addClass("icon_normal");  }');
     
    Was it a bug? Do I have an alternative?
     
     
    Simples CSS
    .icon_normal {
    border:0px solid transparent;
}


.icon_normal:hover {
    border:2px solid transparent;
}

    How to get vertical scroll position of TUniScrollBox

    in General

    Posted

     

    me.body.el.dom.addEventListener...

    function afterrender(sender, eOpts)
{
    var me = sender;
    me.body.el.dom.addEventListener('scroll', function(event) {
        var element = event.target;
        if (element.scrollHeight - element.scrollTop === element.clientHeight) {
            ajaxRequest(me, 'scrolledToBottom', []);
        }
    })
}
    Perfect
     
    My need was to capture when the scroll bar was at the top.
     
    Here's an example.
     
        var me = sender;
me.body.el.dom.addEventListener('scroll', function(event) {
        var element = event.target;


if (element.scrollTop === 0) {
            ajaxRequest(me, 'scrolledToBottom', []);
        }
    })

    Thanks Friend.

    How to get vertical scroll position of TUniScrollBox

    Maybe like this ?!:

     

    1. UniScrollBox1 -> ClientEvents -> ExtEvents -> function afterrender:

    function afterrender(sender, eOpts)
{
    var me = sender;
    me.el.dom.addEventListener('scroll', function(event) {
        var element = event.target;
        if (element.scrollHeight - element.scrollTop === element.clientHeight) {
            ajaxRequest(me, 'scrolledToBottom', []);
        }
    })
}

    2. UniScrollBox1 -> OnAjaxEvent:

    procedure TMainForm.UniScrollBox1AjaxEvent(Sender: TComponent;
  EventName: string; Params: TUniStrings);
begin
  if EventName = 'scrolledToBottom' then
  begin
    AddSomeMoreRows
  end;

end;

     

    Perfect solution for UniScrollBox.
     
    I tried with UniHTMLFrame but it does not work.
    Any suggestion?

    How I can focus a TUniHTMLMemo text?

    Hi,

     

     

    Ok, can you try to use this approach for now ?!:

    //UniHTMLMemo1.JSInterface.JSCall('focus', []);
UniHTMLMemo1.JSInterface.JSCode('if (Ext.isChrome) {'#1'.iframeEl.el.dom.contentDocument.body.focus()} else {'#1'.focus()};');

    Best regards,

    Perfect.
     
    Thank you very much for your attention.

    Synchronous Operations

    in General

    Posted

    I'm doing a "chat" messaging system.

     

    After the user login I make a request to an http server that only responds if a new message arrives or reaches a time limit of 120 seconds.

     

    The problem is that when I make this request unigui is waiting for the response and it is not possible for the user to continue using the application.

     

    I would like to know how to run this http request in the background without freezing the application. Because unigui is waiting for the http server response.

     

     

    Sorry if I can not be very clear because I'm using Google Translate.

    If necessary I can give an example of this situation.

    Hello everyone.

     

    My project is set to EnableSynchronousOperations set to true.

     

    I need to make a request from a json on a remote server, but this call may take some time to get up to 2 minutes.

     

    How to capture this json without freezing my application?

    So while waiting for this json to be captured I can go using the application.

    Hi,

     

    Thanks for the testcase,

     

    Online demo example works for me.

     

    Which browser are you using ?!

     

    I'm using "Google Chrome Version 63.0.3239.132 (Official Version) 64-bit (Last Update)"

    In Internet Explorer 11 there is also a problem.

     

     

    The problem continues even with the code being reported.
    UniSession.AddJS('Ext.defer(function(){Ext.get("'+ UniHTMLMemo1.JSName +'_id-inputCmp-iframeEl").focus()},100)');

    In firefox it works perfectly.

    Hi,

     

    One of the possible solution, while, try:

    procedure TMainForm.UniButton1Click(Sender: TObject);
begin
  UniSession.AddJS('Ext.get("'+ UniHTMLMemo1.JSName +'_id-inputCmp-iframeEl").focus()');
end;

    Best regards.

     

    This code is not working in my project.
    It does not display any errors but the focus is not set.
     
    I am using version 1.0.0.1422.
     
    Any suggestion?

    UniHTMLFrame

    Posted

    Hello Developer thank you very much for your attention.
     
    The problem does not happen when I use the code you entered.
    UniHTMLFrame1.JSInterface.JSCode('Ext.DomHelper.insertFirst(Ext.get("'#1'_id-innerCt"), {tag: "div", cls: "yourCls", html: "<b>N</b>ew line"});');

     

    One last question.
    Do you think it's appropriate to use UniHTMLFrame to create a chat like the example below?
     
    What do you suggest?
     
     

    UniHTMLFrame

    in General

    Posted

    Hello everyone.

     

    I am initiating a chat with the UniHTMLFrame component and some doubts appeared.

     

    1 - How do I make the vertical scroll bar go down or up completely?

     

     

    2 - What better way to add text at the beginning of html?

    I am using the following code. 



    
UniHTMLFrame1.HTML.Text: = 'My Message <br>' + UniHTMLFrame1.HTML.Text;


    3 - After adding a message at the beginning of the html how can I preserve the current position of the scroll bar? "so no matter what text size was added at the beginning of the html, UniHTMLFrame continues to display the same content it was before adding text at startup.

     

     

    Sorry for my bad English.

    And thank you all.
