Hi,

thanks Aki, now I got this working.
(Sorry Aki for the msg send directly to you, I hit "send" too fast...)

I have still a problem.

When implementing -doCommandBySelector:, most keys do what I expect,
but Command-A sends a selector of noop:, not selectAll: as I expected.

What's happeneing ?

never get called, which I suppose are here for handling mouse events and thus the selection ?

The methods are for the input methods showing various information near your text.  Not for general mouse event handling.

You still need to implement the mouse handling for selection with a custom code for your view.

To handle mouse events in a text input friendly way, you want to first pass all mouse events to -[NSTextInputContext handleEvent:].
If the method returned NO (meaning the text system didn't swallow the event), then, you can perform your custom mouse handling logic for that event.

Hi,

I try to write my own text field, for cross-platform dev. reasons I don't have another choice, unfortunately...

So, in my view, I have this:

@interface MyOpenGLView : NSOpenGLView<NSTextInputClient>
...
@end

@implementation MyOpenGLView

- (void) mouseDown: (NSEvent*) iEvent
{
    if( mActiveTextButton )
    {
        [[self  inputContext]  handleEvent: iEvent];
    }
    else
    {
	// this is the crossplatform stuff...
        AddMouseEvent( self, iEvent, ::nWindowingSystem::kClass_MouseClick, ::nWindowingSystem::kClick_LeftDown );
    }
}

the same goes for : mouseDragged:, mouseMoved:, mouseUp:, keyDown: and keyUp: .

I also implemented all the required methods from the NSTextInputClient protocol.

Now I can type accented characters, like é, by typing 'Option-e' then "e'.

But I can't select anything.

- (NSUInteger) characterIndexForPoint: (NSPoint) iPoint
- (NSRect) firstRectForCharacterRange: (NSRange) iRange actualRange: (NSRangePointer) oActualRange
never get called, which I suppose are here for handling mouse events and thus the selection ?

What am I doing wrong ?

Thanks.
