Dear Fons, dear Rooters
Sorrowly, I am still confused:
What do I need to do in order to implement both TGListTree and
TRootIconBox of TRootBrowser as frames embedded in my own
GUI application?
a) Is it possible to create the following class:
class TBrowseFrame: public TGCompositeFrame, public TBrowserImp
Can I then embed this class in my own application?
Does TBrowserImp then call my class TBrowseFrame or does
it always call TRootBrowser?
b) Since all objects which inherit from TObject have a method:
TObject::Browse(TBrowser *b), is it possible to overwrite class
TBrowser with the following class:
class MyBrowser: public TBrowser
Will then class MyBrowser be called?
If I do this, how can I avoid that the constructor of TBrowser
calls: fImp = gGuiFactory->CreateBrowserImp(this, title, w, h);
Thank you in advance for your help
Best regards
Christian
