The OPTTYPE structure describes the set of possible selections for an option item, and the selection method for the set.
Members
cbSize
Size in bytes of this structure.
Type
Specifies the type of the option item. The CPSUI uses Type to determine how to lay out the OPTPARAM selections associated with an OPTITEM option item. This field must be one of the following predefined TVOT_Xxx values.
| Value | Description |
| TVOT_2STATES | There are two option buttons for the item's two possible states. |
| TVOT_3STATES | There are three option buttons for the item's three possible states. |
| TVOT_UDARROW | The item has an up-down control. |
| TVOT_TRACKBAR | The item has a trackbar. |
| TVOT_SCROLLBAR | The item has a scroll bar. |
| TVOT_LISTBOX | The item has a list box. |
| TVOT_COMBOBOX | The item has a combo box. |
| TVOT_EDITBOX | The item has an edit box. |
| TVOT_PUSH BUTTON | The item has a push button. |
| TVOT_CHKBOX | The item has a check box. |
Flags
Bitmask containing a bitwise OR of any of the following values.
| Flag | Description |
| OPTTF_TYPE_DISABLED | Specifies that the array of OPTPARAM structures to which pOptParam points are disabled, meaning that none of the selectable items can be selected. |
| OPTTF_NOSPACE_ BEFORE_POSTFIX |
Specifies that the CPSUI should not add a space character before the postfix string when combining it with the string specified in the pName field of the associated OPTITEM. For example, this bit could be set when the postfix string is "%", so that the percent value and percent sign are displayed without a space between them. This bit is valid only when an associated OPTPARAM item specifies a postfix string. |
Count
Specifies the number of OPTPARAM structures to which pOptParam points. This value depends on the value of Type, and must be set as shown in the following table.
| TVOT_Xxx | Count |
| TVOT_2STATES | 2 |
| TVOT_3STATES | 3 |
| TVOT_UDARROW | 2 |
| TVOT_TRACKBAR | 3 |
| TVOT_SCROLLBAR | 3 |
| TVOT_LISTBOX | n |
| TVOT_COMBOBOX | n |
| TVOT_EDITBOX | 2 |
| TVOT_PUSH BUTTON | 1 |
| TVOT_CHKBOX | 1 |
BegCtrlID
Specifies the start control window ID. Each OPTITEM has a predefined number of control window IDs associated with it. This field must be set to zero if the caller is using the CPSUI's standard pages.
The CPSUI uses BegCtrlID to manage the selections and initializations of an item associated with the caller's dialog box. It uses BegCtrlID only when the OPTITEM is associated with a user-defined DLGTEMPLATE; that is, only when the DlgTemplateID field of the associated DLGPAGE structure is not a standard DP_STD_Xxx template ID.
The caller must organize control IDs based on Type as shown in the following table.
| TVOT_Xxx | Control ID Values |
| TVOT_2STATES | BegCtrlID = 2 States group box ID BegCtrlID+1 = 2 States static title text ID BegCtrlID+2 = State 1 radio button ID BegCtrlID+3 = State 1 icon control ID BegCtrlID+4 = State 2 radio button ID BegCtrlID+5 = State 2 icon control ID BegCtrlID+6 = Extended check box/push button control ID BegCtrlID+7 = Extended check box/push button icon control ID |
| TVOT_3STATES | BegCtrlID = 3 States group box ID BegCtrlID+1 = 3 States static title text ID BegCtrlID+2 = State 1 radio button ID BegCtrlID+3 = State 1 icon control ID BegCtrlID+4 = State 2 radio button ID BegCtrlID+5 = State 2 icon control ID BegCtrlID+6 = State 3 radio button ID BegCtrlID+7 = State 3 icon control ID BegCtrlID+8 = Extended check box/push button control ID BegCtrlID+9 = Extended check box/push button icon control ID |
| TVOT_UDARROW | BegCtrlID = Up-down arrow group box ID BegCtrlID+1 = Up-down arrow static title text ID BegCtrlID+2 = Up-down arrow edit box ID BegCtrlID+3 = Up-down arrow icon control ID BegCtrlID+4 = Up-down arrow postfix static text ID BegCtrlID+5 = Up-down arrow help static text ID BegCtrlID+6 = Up-down arrow's arrow ID BegCtrlID+7 = Extended check box/push button control ID BegCtrlID+8 = Extended check box/push button icon control ID |
| TVOT_TRACKBAR TVOT_SCROLLBAR |
BegCtrlID = Track/Scroll bar group box ID BegCtrlID+1 = Track/Scroll bar static title text ID BegCtrlID+2 = Horizontal Track/Scroll bar ID BegCtrlID+3 = Track/Scroll bar icon control ID BegCtrlID+4 = Track/Scroll bar low range text control ID BegCtrlID+5 = Track/Scroll bar high range text control ID BegCtrlID+6 = Track/Scroll bar postfix ID BegCtrlID+7 = Extended check box/push button control ID BegCtrlID+8 = Extended check box/push button icon control ID |
| TVOT_LISTBOX TVOT_COMBOBOX |
BegCtrlID = List/Combo box group box ID BegCtrlID+1 = List/Combo box static title text ID BegCtrlID+2 = List/Combo box ID BegCtrlID+3 = List/Combo box icon control ID BegCtrlID+4 = Extended check box/push button control ID BegCtrlID+5 = Extended check box/push button icon control ID |
| TVOT_EDITBOX | BegCtrlID = Edit box group box ID BegCtrlID+1 = Edit box static title text ID BegCtrlID+2 = Edit box ID BegCtrlID+3 = Edit box icon control ID BegCtrlID+4 = Edit box postfix static text ID BegCtrlID+5 = Edit box help static text ID BegCtrlID+6 = Extended check box/push button control ID BegCtrlID+7 = Extended check box/push button icon control ID |
| TVOT_PUSH BUTTON TVOT_CHKBOX |
BegCtrlID = Push button/Check box group box ID BegCtrlID+1 = Push button/Check box static title text ID (not used by CPSUI) BegCtrlID+2 = Push button/Check box ID BegCtrlID+3 = Push button/Check box icon control ID BegCtrlID+4 = Extended check box/push button control ID BegCtrlID+5 = Extended check box/push button icon control ID |
pOptParam
Pointer to an array of OPTPARAM structures describing the selections that belong to an OPTITEM item's set.
Style
Specifies the style of the group box for an option item. OTS_LBCB_Xxx styles are applied only to the TVOT_LISTBOX and TVOT_COMBOBOX item types; OTS_PUSH_Xxx styles are applied only to TVOT_PUSH BUTTON types. This field can be a bitwise OR of the following values.
| Value | Description |
| OTS_LBCB_SORT | The CPSUI sorts the listbox or combobox selectable items in ascending order, based on the pData fields of the OPTPARAM structures to which pOptParam points. |
| OTS_LBCB_ PROPPAGE_LBUSECB |
If Type is TVOT_LISTBOX and the selection set identified by this OPTTYPE structure is on a non-treeview user-defined property sheet page dialog box, the CPSUI interprets control for a combobox rather than a listbox. |
| OTS_LBCB_ PROPPAGE_CBUSELB |
If Type is TVOT_COMBOBOX and the selection set identified by this OPTTYPE structure is on a non-treeview user-defined property sheet page dialog box, the CPSUI interprets control for a listbox rather than a combobox. |
| OTS_LBCB_ INCLUDE_ITEM_NONE |
The CPSUI adds Not Available to the list of selections in a listbox or combobox. The CPSUI sets the Sel field of the OPTITEM structure to -1 when a user selects None from the list. It also validates Sel during page initialization, setting any out-of-range values to -1. |
| OTS_LBCB_ NO_ICON16_IN_ITEM |
The CPSUI does not include icons in the listbox or combobox. By default, each item string in a listbox or combobox has a 16x16 icon placed in front of it. |
| OTS_PUSH_ INCLUDE_SETUP_TITLE |
The CPSUI appends "Setup" to the push button's text string. |
| OTS_PUSH_ NO_DOT_DOT_DOT |
The CPSUI does not append "…" to the text string on a push button. |
| OTS_PUSH_ENABLE_ALWAYS | Regardless of permissions, the CPSUI allows the user to select the push button. The associated callback or dialog box procedure should display the current setting but not allow the user to modify it. |
wReserved[3]
Reserved; these fields must be set to zero.
dwReserved[3]
