Help with c++ syntax for wxcheckbox

[papafreebird]

I'm starting to code using linux codeblocks IDE and GCC compiler to create a wxwidgets gui. I have experience coding gui's in c++ builder 6 with no problems but now that I am trying to code in linux for linux I'm having issues with the syntax.

What works in c++ builder doesn't work in codeblocks.

the following is a c++ builder script that works for what I want.

if (CheckBox14->Checked==true)

{
CheckBox13->Enabled=false;
}

else if (CheckBox14->Checked==false)
{
CheckBox13->Enabled=true;
}

Here is what I have so far that works in codeblocks.

if (fast->IsChecked())
{
normal->Disable();
best->Disable();
}
else if (fast->What do I put here for unchecked?)
{
normal->Enable();
best->Enable();
}

Notice that I am stumped as to what syntax to use for the "else if " statement. I have tried
fast->IsChecked==fal se
fast->UnChecked==fal se
fast->IsChecked(fals e)

and none work. Any help would be appreciated.

Edit~~ Okay I figured it out fast->IsChecked()==f alse worked great.
I would still like a link to a good wxwidgets c++ tutorial or a good wxwidgets c++ book.

Also If you know of any good books or links to tutorials I would be very much grateful.
