Window Properties

TDialog also provides functions that let you change resources and properties of the interface element.

Because TWindow provides generic functionality for a large variety of objects, it does not provide very specific functions for resource and property manipulation. High-level objects provide much more specific functionality. But that specific functionality builds on and is in addition to the functionality provided by TWindow:

• SetCaption() sets the window caption to the string that you pass as a parameter.
• GetWindowTextTitle() returns a string containing the current window caption.
• SetCursor() sets the cursor of the instance, identified by the TModule parameter, to the cursor passed as a resource in the second parameter.
• You can set the accelerator table for a window by assigning the resource ID (which can be a string or an integer) to Attr.AccelTable. For example, suppose you have an accelerator table resource called MY_ACCELS. You would assign the resource to Attr.AccelTable like this:

  TMyWnd::TMyWnd(const char* title)
  {
   Init(0, title);
   Attr.AccelTable = MY_ACCELS; // AccelTable can be assigned
  }

The TWindow::Init() function in this example is used to initialize a the base class of a derived window class.
