wxPython: how to update a panel content/layout according to a variable content

[Lo?c Mah?]

Hello

I have a problem to update the content of a wx.Panel already displayed
after changing a variable, used to define the wx.Panel content.

I have the following elements in my code:

DataList: is a list containing some data

CustomPanel: is a derived class of wx.Panel,
it contains one sizer which contains a smaller panel for each
element of the DataList list
After having displayed CustomPanel on the screen, the elements in
DataList change (after a user action like clicking on button)

I would like to refresh the CustomPanel to take into account the
changes of the DataList list
Is there a kind of Refresh/Update function which could update the
CustomPanel so
that evry sizers and panles contained by this CustomPanel are redrawn
according to the current value of DataList ?
or do you have to write your own update/refresh method for Panel and
Windows objects ?
and are you obliged to detroy the CustomPanel object and re-create a
new one?
I would appreciate any hint/reference to do this, and also a code
sample if possible.

Thanks.

wxWindow has Update and Refresh methods. You can override the one of your
wxPanel, where you can call all its children to update/refresh themselves.
wxPanel's update could be triggered by a timer event, mouse event or
whatever.

I do such things preferably in timers owned by the widgets themselves.

Thanks for the answer.

I will try the method you talked about.

For the moment, I am creating a new sizer and new panel
and call the SetSizer(...) and SetAutoLayout(...)
but this is not satisfying me.
