In this section:
Format windows, created using winio@, contain text and child windows called controls. Text and controls are presented in the order in which they appear in the format string. ClearWin+ automatically positions the text and controls in a window and adjusts the size of the window to suit its contents. This automatic positioning provides for a standard blank border within the window. This border surrounds all the text and controls. It can be removed by using %ww (Window Style) together with its no_border option.
Text and controls in a format string can be separated by one or more of the following format codes.
|
gives a new line |
|
|
advances to the next tab position |
|
|
advances to the left margin below any existing controls |
|
|
centres text and controls on the current line |
|
|
right justifies text and controls on the current line |
%ta (Next Tabstop) and %nl (Newline) can be used with an integer modifier. For example, %2nl gives two new lines.
It is important to note that, if these codes appear within a %ob (Open Box) box, then the effect relates to the box rather than the window as a whole. Moreover, %ob (Open Box) boxes can be nested. As a result it is possible to exercise a fine control over the positioning of items within a window. In extreme cases, there are other mechanisms for adjusting the position of a given item.
