events not working with pascal about pascal-webui HOT 21 CLOSED

webui 7.zip please see attach lazarus project , it is not working no feedback

I see three main problems at first glance: 1. In Lazarus, you need to create a project of the "simple program" type; 2. In the project parameters, set the target processor family to x86_64, since the library webui.dll - 64 bit; 3. When installing the hook, the name is case sensitive, in your case it is myid and MyID, you need to bring them to the same denominator

if you could share working example

First we need to update pascal wraper to the latest version of the library and only then write an example for Lazarus/Delphi based on it.

I'll take care of it.

we need to update pascal wraper to the latest version of the library

updated the wrapper version to library version 2.4.0, I'll try to do an example on the weekend

thanks Delphius , we would like to ask you to add the sample if you are free

Thank you @delphius for reporting this. Please open two issues. One for Yandex browser, and another for the headless mode.

About the pre-built libs, @ttytm implemented a nice CI to auto build and generate binaries when a new stable release tagged. For now, you should build the lib from source using any C99 compiler (No other dependencies are needed).

If you want to save time, this is my latest build in debug mode, so you can copy the logs from your terminal.

program project1;
{$mode objfpc}{$H+} uses {$IFDEF UNIX} cthreads, {$ENDIF} Classes,WebUI,Dialogs,Interfaces { you can add units after this };
var window: size_t;
procedure EventHandler(e: Pwebui_event_t);
begin
    //writeln('Received callback: ', e^.data);
    ShowMessage('hello');
end;
begin
    window := webui_new_window; webui_show(window, '1.html');
    webui_bind(window, 'myid', @EventHandler);
    webui_wait;
end

doesnt work

What error message do you see?

Can you use an example to see if it's working?

from pascal-webui.

no error message , it just nothing happen when i press the button

from pascal-webui.

No errors when you use your code, I see. And what about the example? Any errors?

from pascal-webui.

no , can you modify my code and show message/show dialog when you press a button

from pascal-webui.

You should use webui_bind() before webui_show().

program project1;

{$mode objfpc}{$H+} uses {$IFDEF UNIX} cthreads, {$ENDIF} Classes, WebUI, Dialogs, Interfaces { you can add units after this };

var window: size_t;

procedure EventHandler(e: Pwebui_event_t);
begin
    // writeln('Received callback: ', e^.data);
    ShowMessage('hello');
end;

begin
    window := webui_new_window;
    webui_bind(window, 'myid', @EventHandler);
    webui_show(window, '1.html');
    webui_wait;
end

this all has been considered , but still not working , if you could share working example , ie press on the button showmessage

Lazarus Example

@hassandraga, I usually have a Yandex browser running, so webui selects it to launch the window, I looked at the mechanism in the source codes of the library. When testing a new version of the library, such a thing happens, if the Yandex browser is running, then webui_show simply opens windows Explorer in the folder C:\Users and that's it. If you unload Yandex, the library loads chrome by default and everything is ok. I haven't checked other browsers yet, there's no time.

if necessary, I can open the issue, but first I would like to understand if this is really a library error or something else.

And one more thing, pascal wrapper is already for 2.4.0, and in releases you can download dll only for 2.3.0. I downloaded 2.4.0 in the discussions and use the current dll in the examples, but I think not everyone will be able to figure it out, the main problem is that there is no backward compatibility for key structures, for example Pwebui_event_t, so it is very important to use the correct version of the binary library

And one more question, we use webui in headless mode to test pages from pascal, while in order to load the pages themselves, we have to use tricks such as this one:
webui_show(Window, '<!DOCTYPE html><html><head></head><body><script>function loadData(){fetch("linktosomehost.com").then(response=>response.text()).then(content=>{document.open("text/html");document.write(content);document.close()}).catch(error=>{console.error(error);});}window.onload=loadData;</script></body></html>');
to let webui to load the necessary library code on the browser side to serve events and websocket and it can be also done by dom manipulating.
I certainly understand the true purpose of the library, but since the possibility of working in headless mode has already been implemented, maybe we should think about a more efficient way of working in this mode?

thanks delphius , could we use showmessage instead of writeln?

from pascal-webui.

thanks delphius , could we use showmessage instead of writeln?

these are just training examples, if the output goes to the console, then it is better to output to the console, otherwise you will have to pull the entire lcl behind you to connect dialogs

yes actually i had done that , but when i press it didnt show message

from pascal-webui.

yes actually i had done that , but when i press it didnt show message

wouldn't it be easier then to use the usual lazarus form instead of the console?

wouldn't it be easier then to use the usual lazarus form instead of the console?

the idea is to mix the beauty of HTML5 & CSS and the power of fpc and lcl , like using printers , reports , dialogs ....etc

Im closing this as everything is working. Sample project provided is invalid, element IDs are case sensitive.
