Slowness to create widgets

EdsonSil_Sil · March 26, 2014, 1:57pm

Hello!

A help please.

In the example below because creating controls is much faster than the frame on the page of the book?

thank you

( python 2.7 and wx.python 2.8 )

The slowness in the creation of wx.TextCtrl also occurs using wx.Notebook.

Could someone help me?

Hi,

The slowness in the creation of wx.TextCtrl also occurs using wx.Notebook.

Don't understand why it is that much slower, but adding a Freeze/Thaw helped a lot:
2.9.5.0
Frame: 0.0499999523163
Page: 0.0560002326965

Before I had 2.5 something for the Page.

Attached the modified version.

By the way PySimpleApp() is deprecated in Phoenix and not really needed in recent wxPython versions, so either use just wx.App or the WIT -http://wiki.wxpython.org/Widget%20Inspection%20Tool.

Hello Werner,

Improved with the Freeze / Thaw.

Another interesting detail is that if you add the attribute pos = (200,100) in wx.TextCtrl (oParent, -1, “”, (200, 100), size = (200, 22)), also accelerates the creation.

Hey Werner, how did you profile just adding the page? (or both, really).

Thanks,
Che

That's weird as this means that it has to work even more, i.e. you position it and then the sizer kicks in and does its work, i.e. it most likely moves it again.

Nothing fancy just a timeit call around the method call.

Hi Werner,

Puts the pos in your example and compares the creation time. Is incredibly faster.

thank you
