wx.html.HtmlWindow and wxpTag, how to fetch all user input at once ?

wxPython Users

hello,

I've a html page with embedded wx-controls,
through wxp tags.
I show these pages in wx.html.HtmlWindow,
which works very nice.

On these pages there are several controls, like a few wx.TextCtrl.
Now what ever the user puts into these controls,
I want to grab that in one time,
preferable without extra user interaction, so for instance when the user leaves the page.

Now I saw a previous question in the list related to my question,
about retrieving a checkbox.

<wxp module="wx" class="CheckBox">
    <param name="label" value=I> <param name="id" value=5100>
</wxp>

checkbox=myhtmlwin.FindWindowById(5100)

But that's not a very elegant way,
certainly if you don't know the content of the page at forehand :wink:

So the questions are:
- is there a way to find all wxp controls on a page (other than parsing the source string :wink: ?
- if these controls can be found, can I get to know there type ?
- I can detect leaving the page from some button presses,
but is there a way to get notified when the page is left ?

thanks,
Stef Mientki

theHtmlWindow.GetChildren() will return a sequence of the child widgets of the window. You can iterate through that sequence and grab the values or nearly whatever else you want to do.

- if these controls can be found, can I get to know there type ?

You can look at child.__class__ or use isinstance()

- I can detect leaving the page from some button presses,

Not directly, but you can catch the link clicked events to know when the page is being left by some means other than your buttons.

thanks Robin,

works like a charm.
Still wonder why "GetChildren" doesn't popup in my autocompletion list ?

cheers,
