Detailed Description

MDI tab control (MC_WC_MDITAB).

This control is a replacement for standard multiple document interface (MDI), as that interface seems to be outdated, and does not reflect modern GUI requirements.

Instead this control provides user experience similar to the web browsers with tabbing support.

The control is very similar to the standard tab control from COMCTL32.DLL, both visually and from developer's point of view. There two main differences:

• MC_WC_MDITAB does not have the main bodyfor contents of the tab; i.e. the contents of the tab is not really rendered in child window of the MC_WC_MDITAB control.
• The contol laso provides few auxiliary buttons on it. They might be invisible depending on the control style and internal state. There is a button to close the current tab, to show pop-up menu of all tabs and finally buttons scrolling the tabs to left or right if there are too many.

Styles, messages and notifications the control supports mostly correspond to subset of messages and styles of the standard tab control. The counterparts have generally also the same names (differing only in prefix of the identifiers). If you are familiar with the standard tab control, you should be able to adopt MC_WC_MDITAB very quickly. However please note that the messages and styles are not interchangeable: The constants of styles and messages generally differ in their values.

Although the purpose of the control is to provide a replacement for the MDI, the programmatic interfaces very differs. If you want to replace MDI with this control in an existing application, expect it will take some time.

• In MDI, the child MDI windows can be minimalized or restored so they would not cover whole MDI client window. MC_WC_MDITAB control does not provide any replacement for this (anyway only very few users rarely used this feature of MDI). If your application needs to allow access to multiple documents simultaneously, you need to develop in other way with the MC_WC_MDITAB (e.g. to allow having multiple top level windows, each with the MC_WC_MDITAB to manage the documents open in each particular window).
• MDI absolutely expects that the application has its submenu Window, with all the commands like Tile horizontally or vertically, or too select another MDI document. MC_WC_MDITAB control does not expect that (still you are free to implement any menu you like ;-)

These standard messages are handled by MC_WC_MDITAB control:

• WM_GETFONT
• WM_SETFONT
• WM_SETREDRAW
