It would be better if wxSpinCtrl can mark its value validated and selected after press enter

Post by JohnKnow »

In some case, I need change a value frequently to see it effect.
wxSpinCtrl now only mark its value validated after lose focus, while I need change its value again and again. It's not convenient.

I think wxSpinCtrl will be better with below two features:
1. Update value after press enter, and make its value selected will be convenient to change it again.
2. Add a property to set the change step after press its arrow button. Some times it value range is bit, change it 1 by 1 is two slow.
No, I know everything.

I think both issues could be solved by subclassing wxSpinCtrl and handling (and then skipping) the wxEVT_TEXT_ENTER and wxEVT_SPINCTRL events.
Use the source, Luke!

Hi,
Problem 2 can be solved by using wxSpinCtrlDouble.

Thank you.

Was that just a statement or a request for help regarding this task?

Just so you know...

Unlike for a textbook C++ class, subclassing a wxWidgets control may not be easy, as there may be different implementation (classes) for individual platforms, which just have the same public interface but their internals can considerably differ.

Looking at the docs, there are no documented virtual methods to override in wxSpinCtrl...

Hi PB,
I see, wxSpinCtrl has no virtual method. But it is drived from wxEvtHandler.
I guess, it could be possible to subclass it and add an event handler to its event table, or just bind a handler function to the control.

I will try it, or just change the official code then request to pull when I'm free. I have to live with it now because I'm rushing for my work :D
