[Wxlua-users] wxLuaHtmlWindow how to catch the event?

From: Steve K. <ha...@ya...> - 2006-05-29 10:31:26

Hi everyone,

I am playing with the sample htmlwin.wx.lua. What I want is to catch the event frm the object embeded in the html window. So far, failled :-)

What I did is replace the text box widgets with a button, with an ID and then use ConnectEvent as normal 

frame:ConnectEvent(button_ID, wx.wxEVT_BUTTON_CLICKED,  OnCLickFunc)

(Still use version 2.6.2.0 so ConnectEvent is right )

it seems the event is not fired, or not traverse upward to the frame. Even I use html:ConnectEvent; not work as well.

How can I make it work or is it impossible?

Note: The similar work in c++ though

Thanks in advance

Cheers,

Can you post a little bit of code to show how it should work and what
I should expect to see based on your C++ tests. I have never used the
HTML widget in lua or C++.

Hi,

I have a minimum simple script to show as below:

frame=wx.wxFrame(wx.wxNull, 10001, "test")
--frame:ConnectEvent(10001, wx.wxEVT_ENTER_WINDOW, function (event) print"Enter work" end) 
--frame:ConnectEvent(10001, wx.wxEVT_LEAVE_WINDOW, function (event) print"Leave not work" end) --not work
--frame:ConnectEvent(10001, wx.wxEVT_MOTION, function (event) print"Motion Work" end)
--frame:ConnectEvent(10001, wxEVT_LEFT_DCLICK, function (event) print"Not work" end)
--frame:ConnectEvent(10001, wxEVT_LEFT_DOWN, function (event) print"Left down not work" end)
--frame:ConnectEvent(10001, wxEVT_LEFT_UP ,function (event) print"Left up not work" end)
--frame:ConnectEvent(10001, wxEVT_RIGHT_DCLICK ,function (event) print"Right dclick not work" end)
--frame:ConnectEvent(-1, wxEVT_RIGHT_DOWN ,function (event) print"Right down not work" end)
--frame:ConnectEvent(-1, wxEVT_RIGHT_UP ,function (event) print"Right up not work" end)
frame:Center()
frame:Show(true)

Pls note that the above script, the equivalent C++ work as expected. I have tested it using Dialogblocks; add one frame and add the event accordingly.


This one is not related to html window at all

And the HTML window; as you suspect from the above one;  it work with wxEVT_COMMAND_BUTTON_CLICKED  but not with  wxEVT_BUTTON_CLICK  or wxEVT_LEFT_DCLICK. I have not tested it with another kind of event.

      
frame = nil html  = nil htmlTextPage = [[<html>                    <head>                    <title>Not working</title>                    </head>                    <body>                         <h3>wxHtmlWidgetCell demonstration</h3>                         There are three bound widgets below.                         <hr>                         <center>                             <lua text="first widget"                                 x=100 y=70>                         </center>                     </body>                  </html>]] function main()     -- create the frame window     frame = wx.wxFrame( wx.wxNull,                         wx.wxID_ANY,                         "HtmlWindow Demo",                         wx.wxDefaultPosition,                         wx.wxSize(450, 450),                         wx.wxDEFAULT_FRAME_STYLE )     -- create a simple file menu  -- THIS WORKS                         --   frame:ConnectEvent(30000, wx.wxEVT_COMMAND_BUTTON_CLICKED,

From: Steve K. <ha...@ya...> - 2006-05-30 01:19:17

OOPS  My mistake it should prefixed with wx.

So most of them works but  not  wxEVT_LEAVE_WINDOW

      
frame=wx.wxFrame(wx.wxNull, 10001, "test")
--frame:ConnectEvent(10001, wx.wxEVT_ENTER_WINDOW, function (event) print"Enter work" end) 
frame:ConnectEvent(10001, wx.wxEVT_LEAVE_WINDOW, function (event) print"Leave not work" end) --not work
--frame:ConnectEvent(10001, wx.wxEVT_MOTION, function (event) print"Motion Work" end)
--frame:ConnectEvent(10001, wx.wxEVT_LEFT_DCLICK, function (event) print"work" end)
--frame:ConnectEvent(10001, wx.wxEVT_LEFT_DOWN, function (event) print"Left down work" end)
--frame:ConnectEvent(10001, wx.wxEVT_LEFT_UP ,function (event) print"Left up work" end)
--frame:ConnectEvent(10001, wx.wxEVT_RIGHT_DCLICK ,function (event) print"Right dclick work" end)
--frame:ConnectEvent(-1, wx.wxEVT_RIGHT_DOWN ,function (event) print"Right  work" end)
--frame:ConnectEvent(-1, wx.wxEVT_RIGHT_UP ,function (event) print"Right up  work" end)
frame:Center()
frame:Show(true)
For the HTMLWIndow I think the COMMAND EVENT works but not for mouse event which is natural for a button, thus I think it is ok

Sorry for a big noise. :-)

ANyway the wx.wxEVT_LEAVE_WINDOW not work which I do not understand yet..

Events like mouse and wxEVT_LEAVE_WINDOW need to be connected directly
to the window. The rule is that if the event is not derived from a
wxCommandEvent it won't travel up the event handler chain. You can
also tell by the event macro signature, for example
EVT_LEAVE_WINDOW(func) doesn't take an id.

Try:
button:Connect[Event](10001, wxEVT_LEAVE_WINDOW, function(event)
print("Bye.") end)
Or
button:Connect[Event](wx.wxID_ANY, wxEVT_LEAVE_WINDOW, function(event)
print("Bye.") end)

The latter may be required for some reason, that is a wxWidgets issue however.

Thanks for your reply.
Just abit of adamant,  why the following code in c++ works as expected?

      
#include "wx/wx.h" #include "wx/frame.h"  class test: public wxFrame {         DECLARE_CLASS( test )     DECLARE_EVENT_TABLE()     public:     test( wxWindow* parent, wxWindowID id = -1, const wxString& caption = _("Test"));     void OnLeaveWindow( wxMouseEvent& event ); };  IMPLEMENT_CLASS( test, wxFrame ) // Is the following equivalent to frame:ConnectEvent(wx.wxEVT_LEAVE_WINDOW, OnLeaveWindow)   ? BEGIN_EVENT_TABLE( test, wxFrame )     EVT_LEAVE_WINDOW( test::OnLeaveWindow ) END_EVENT_TABLE()  test::test( wxWindow* parent, wxWindowID id, const wxString& caption ): wxFrame( parent, id, caption){} void test::OnLeaveWindow( wxMouseEvent& event ){ wxMessageBox(_("Leave window in c++; works"));  }  class ClGUIApp: public wxApp {         DECLARE_CLASS( ClGUIApp )     DECLARE_EVENT_TABLE() public:     ClGUIApp();     virtual bool OnInit();     virtual int OnExit(); }; DECLARE_APP(ClGUIApp) IMPLEMENT_APP( ClGUIApp ) IMPLEMENT_CLASS( ClGUIApp, wxApp ) BEGIN_EVENT_TABLE( ClGUIApp,
 wxApp ) END_EVENT_TABLE() ClGUIApp::ClGUIApp(){} bool ClGUIApp::OnInit() {     test* mainWindow = new test( NULL, -1 );  mainWindow->SetSize(400,300);     mainWindow->Show(true);      return true; } int ClGUIApp::OnExit(){        return wxApp::OnExit(); }

This is kinda' hard to read. :/

Take the choices.wx.lua sample, add the line to the leave window.

 frame:SetStatusText("wxEvents from contols will be displayed here", 0)
 frame:Connect(wx.wxEVT_LEAVE_WINDOW, function(event) print("Hi") end)

It works for me. Remember that the frame is mostly hidden by the
notebook so you have to find a spot where it's exposed. Try it out for
the listbox as well.

Yes the EVT_LEAVE_WINDOW( test::OnLeaveWindow ) is similar to
wxEvtHandler::Connect. There are some differences however. The Connect
function uses a dynamic event table that is processed before (IIRC)
the static event table generated with the macro so you have to use
event:Skip() to get the default processing to work in some cases.
