Lines 78 . . . 82 If there were no errors adding the dynamic elements to the
pop-up (memory full), we execute the pop-up and display
the results as with the dialog box.
Lines 83 The memory for this pop-up was created dynamically so it
must be freed when we are done with it.
Lines 86 . . . 88 One additional menu item lets the user change the font for
our window.
Lines 89 . . . 91 Any messages we do not handle must be passed onto the
system so they get handled by someone.
Line 95 All dialog boxes must have a call-back function.
Lines 97 . . . 102 Our predefined menu IDs used by both app1.c and appr1.r.
Lines 104 . . . 106 Our resource file, it includes our predefined menu IDs and
the standard include file tiams.h also.
Lines 108 . . . 116 TOOLBOX defines a menu. The RC_NO_IDS flag says we
will assign all menu IDs. A 0 tells the resource compiler to
use the names we give as symbolic menu IDs and assign
them sequential values.
Line 118 We define a 180 by 70 pixel dialog box with a call-back
function named NoCallBack (defined on line 95).
Lines 119, 120 There are two text edit fields each 10 characters in length
with space for 11 characters displayed (the extra space
means the edit field will not scroll when the last character is
hit). The first edit field will start at offset 0 of the buffer we
pass to the
Dialog
function and the next edit field will start
at offset 11 (must leave room for the zero byte terminator).
Each edit field starts 12 pixels from the left edge of the
dialog box and the first edit field starts 14 pixels from the
top while the second edit field starts 24 pixels down.
Lines 121, 122 There are two pop-ups with coordinates spaced the same as
the edit fields (12 pixels from the left edge and 10 pixels
apart).
Lines 126 . . . 134 The pop-ups for the dialog box are defined here (they can
also be used separately as static pop-ups).
This example can be built using the TI
FLASH
Studio™.
