Questions about WebView

Postby Natter » Wed Nov 23, 2022 1:12 pm

Hi,

1. In IE I can get the web page document so oIE:GetProp("Document"). Can I do this in WebView ?
2/ There is a Navigate method in the WebView class. Is it possible to use it to download HTML text from a file ?
3. When I launch WebView, a standard window opens. Is it possible to change its type to PopUp ?
4. Is it possible to embed this window in a window with an FW application (in the specified coordinates) ?

Dear Yuri,

Please try this:

1.
Code: Select all  Expand view
function Main()

   local oWebView := TWebView():New(), aaa

   oWebView:bOnBind = { | cJson, nCalls | MsgInfo( cJson, nCalls ) }
   oWebView:Bind( "SendToFWH" )
   oWebView:Navigate( "https://your_url.com" )
   Sleep( 200 )
   oWebView:Eval( 'window.onload = function () { SendToFWH( document ) }' )
   oWebView:Run()
   oWebView:Destroy()

return nil
regards, saludos

2. Simply use this code in your HTML:

<a href="test.txt" download>Click here</a>

3 and 4.:

Class TWebView provides a Method SetParent( oWnd ) so you can make it child of any window, dialog or control :-)

In I create a WebView and in the script I open a new page
var pdg= new URL('MyPage') ;
I need to return some data to the FW on the page URL change event. How can I do this?

Dear Yuri,

When you use this code:
viewtopic.php?p=255632&sid=1d500740664e0671278e8d3f3076d61a#p255632
you can call SendToFWH( params... ) from the web HTML javascript and your FWH app will get it on the oWebView:bOnBind codeblock

1. Is it possible to ask for an example script in the method :Eval() of several lines
2. Why the method is needed :setHtml if you can't write a JS script in it ?

Dear Yuri,

> 1. Is it possible to ask for an example script in the method :Eval() of several lines

Call a function from inside the codeblock where you can easily use multiple lines of code

> 2. Why the method is needed :setHtml if you can't write a JS script in it ?

Of course that you can use JS script in the cHtml that you provide to Method SetHtml(). I am going to provide you an example
regards, saludos

A good example !
What is the method for :oWebView:SetUserAgent(), the program also works without it ?

Dear Yuri,

Method SetUserAgent() is a workaround to be able to login into your goggle account.
Without it you can't login into gmail, etc

Can I use WebView to do the following:
a) Open a page
b) find an item on this page
c) click on this item

All this is easy to do via IE (Activex), but it does not work on WebView :(
