hook WTextEdit events

Added by Mark Petryk 2 months ago

I am trying to 'hook' a WTextEdit event, and get a signal sent back to Wt. I have never worked with JSignal or anything, so I'm a little bit off the range here, any help is appreciated.

I would like to signal Wt anytime a key is pressed in the tinymce editor. I have this code so far and it works;


3298   m_textEdit->·
3299     rendered().connect( [=]()·
3300     {·
3301       std::cout << __FILE__ << ":" << __LINE__ << " " << std::endl;·
3302 ·
3303       auto js =·
3304         Wt::WString::tr( "textedit.js" )·
3305         .arg( m_textEdit-> jsRef() )·
3306         .toUTF8()·
3307         ;·
3308 ·
3309       std::cout << __FILE__ << ":" << __LINE__ << " " << js << std::endl;·
3310 ·
3311       Wt::WApplication::instance()-> doJavaScript( js );·
3312 ·
3313 ·
3314     });·

3563   <message id="textedit.js">·
3564     <![CDATA[·
3565     {1}.ed.onKeyPress.add( function() { alert('blur'); } );·
3566     ]]>·
3567   </message>·

src/Dbo/JobEditor/JobEditor.cpp:3309 

    Wt4_2_1.$('o9nps4d').ed.onKeyPress.add( function() { alert('blur'); } );

What I would like to do is, instead of opening an alert in the browser, I would like to send a signal back to Wt so my server knows a key has been pressed on that widget. Can someone guide me to getting a signal back from the browser?
