DialogAddStaticPulldown | Function (Macro) |
dialogs.h |
HANDLE DialogAddStaticPulldown (HANDLE Handle, short flags, short x, short y, const char *label, void *Popup, unsigned short index); |
Adds a static pulldown/popup menu into a dialog box.
DialogAddStaticPulldown uses the pointer Popup to a static pre-filled
popup menu structure (popup menus and dialog pulldowns are in fact the same
structure) and adds this pulldown menu to the dialog structure associated with
the handle Handle at the position (x,y), where the
coordinates are relative to the top-left corner of the dialog box.
label is the label which will appear in front of the popup menu (or ""
if you don't want any name), and Popup is a prefilled static
popup structure (i.e. you must write
this popup in your source code; for dynamic pop-ups use
DialogAddPulldownEx) of the
associated menu. See menus.h for more info about
creating static popups. The text must fit into one line of the dialog box.
The parameter index determines where the result value of executing the
pulldown menu will be stored, and also indicates what the initially selected
option will be. See DialogDo for information on
how and where the result values are actually stored.
The order of item creation is very important, as it automatically gives each
item an identification number (the first created item will get an
identification number of 0, the second one will get 1, and so on). Every
function that creates an item (i.e. every function beginning with
'DialogAdd...') will increase this identification number.
DialogAddStaticPulldown works like
DialogAddPulldownEx, but only accepts
a static pre-filled dialog Popup instead of a handle.
The parameter flags can be a combination of the following, defined in
the DialogFlags enumeration:
DF_SCROLLABLE | Set this flag if you want this item to be scrollable in a scroll region. |
DF_SKIP | This item is skipped when browsing through items with the arrow keys. |
DF_SCREEN_SAVE | The dialog code saves the area underneath the dialog box when it is started, DB_MEMFULL returned if it cannot. If you wish to use this flag, you must then set it with the first item you created in the dialog box. |
DF_TAB_ELLIPSES | Lines the item up on the right side of the dialog, and draws '......' between the item and its label. This flag is used in the TIOS 'MODE' dialog, for example. It is the default on AMS 1.xx. |
DF_TAB_SPACES | AMS 2.00 or higher: Like DF_TAB_ELLIPSES, but does not draw any dots. |
DF_POPUP_RADIO | AMS 2.00 or higher: If this flag is set, the item looks like a normal pulldown menu that you can select, but when you press the right arrow key, it does not pop up as usual, but returns control to the dialog callback function. This enables the programmer to do whatever he/she wants. For example, in the 'MODE' dialog, setting custom units pops up another dialog instead of a pulldown menu. |
