NAME: SPIN_GROUP
|
|
|
|
SYNOPSIS: This is a custom control object which consisted of
|
|
two buttons. One is an up arrow and one is the down
|
|
arrow. It assoicated the 2 buttons with a list of
|
|
SPIN_ITEM objects. By using the 2 buttons, the user
|
|
can increases or decreases the value of the specified
|
|
SPIN_ITEM control.
|
|
|
|
INTERFACE:
|
|
SPIN_GROUP () - constructor
|
|
~SPIN_GROUP () - destructor
|
|
|
|
AddAssociation()- associated a SPIN_ITEM control with
|
|
the SPIN_GROUP
|
|
IsModified() - return the flag which indicated whether
|
|
the SPIN_GROUP have been modified or not.
|
|
SetModified() - Set when the spin button's field(s) is
|
|
modified by the user.
|
|
SetControlValueFocus() - highlight the current focus.
|
|
|
|
DoChar() - handle the incoming WM_CHAR message
|
|
JumpNextField() - jump to the next spin item field
|
|
JumpPrevField() - jump to the previous spin item field
|
|
DoNewFocus() - a spin item receive focus
|
|
DoArrowCommand() - the spin button receive arrow command
|
|
ChangeFieldValue() - change the current focus field value
|
|
SetFieldMinMax() - set the current focus field to either
|
|
min or max
|
|
|
|
PARENT: CONTROL_GROUP
|
|
|
|
USES: DLIST, ARROW_BUTTON, SPIN_ITEM
|
|
|
|
CAVEATS: There are 2 kinds of spin button in the BLT package.
|
|
1. SPIN_GROUP within a dialog box
|
|
The programmer should specified each individual
|
|
SPIN_ITEM control in the *.rc file. The resource file
|
|
should also included the definitation of the
|
|
SPIN_GROUP. The program will base on the location
|
|
of the SPIN_GROUP to create the Up and Down arrow.
|
|
Therefore, the programmer does not need to specify
|
|
the up and down arrow buttons in the resource file.
|
|
However, the programmer still need to pass the CID
|
|
of the 2 buttons to the SPIN_GROUP constructor.
|
|
|
|
2. SPIN_GROUP in an app window
|
|
In the constructor, the user should specified the
|
|
location and size of the spin button.
