Hello,

I'll start off by saying I'm using an older version of the library; this may have already been addressed in the current code. If so, great and please disregard.

I was trying to create a modal task dialog that had a 48x48 icon. I was very surprised to see that the size of the icon is always hard-coded to be 32x32, even when forcing the use of the CodeJock task dialog implementation and not the native Windows version.

What's worse, is that the CXTPTaskDialog class, despite having a member variable that defines the size of the icons makes it almost impossible for a derived class to change it in a reliable way.

There's a few ways of implementing this, all of which are trivial. You could, for example, make CXTPTaskDialogClient::RefreshMetrics a virtual function. Or you could have an explicit SetMainIconSize function. Or you could make the existing SetMainIcon accept a CSize parameter or call GetIconInfo to retrieve the actual size of the loaded resource.

It's a small thing, but it's the small things that count sometimes.

Thanks,

Nik B.

Hi,

We alerady wrote that main porpose of CXTPTaskDialog class is to provide interface to system Windows7/Vista builtin TaskDialog and create same Dialog for older OS.

System TaskDialog don't have way to change Size of Icon so we can't add such method too for System version.

experienced users can indeed override RefreshMetrics (in last release its already virtual) and disable system task usage for all OS.
