color.h

TColor is a support class used in conjunction with the classes TPalette, TPaletteEntry, TRgbQuad, and TRgbTriple to simplify all Windows color operations. TColor has ten static data members representing the standard RGB COLORREF values, from Black to White. Constructors are provided to create TColor objects from COLORREF and RGB values, palette indexes, palette entries, and RGBQUAD and RGBTRIPLE values. See the entries for NBits and NColors for a description of TColor-related functions.

Public data members

static const TColor Black;

The static TColor object with fixed Value set by RGB(O, 0, 0). See the RGB Windows macro for more information.

static const TColor Gray;

Contains the static TColor object with fixed Value set by RGB(128, 128, 128).

static const TColor LtBlue;

Contains the static TColor object with the fixed Value set by RGB(O, 0, 255).

static const TColor LtCyan;

TComboBox class combobox.h

TextLen

Constructor

You can use TComboBox to create a combo box or a combo box control in a parent TWindow, or to facilitate communication between your application and the combo-box controls of TDialog. TComboBox objects inherit most of their behavior from TListBox. This class is streamable.

There are three types of combo boxes: simple, drop down, and drop down list. These types are governed by the style constants CBS_SIMPLE,

CBS_DROPDOWN, and CBS_DROPDOWNLIST. These constants, supplied to the constructor of a TComboBox, tell Windows the type of combo box element to create.

Public data members

WORD TextLeni

Contains the length of the text in the combo box's associated edit control.

Public constructors

TComboBox(TWindow *parent, int Id, int x, int y, int w, int h, DWORD style, WORD textLen, TModule* module = O)i

Constructs a combo box object with the specified parent window (parent), controlID (Id), position (x, y) relative to the origin of the parent window's client area, width (w), height (h), style (style), and text length (textLen).

Invokes the TListBox constructor with similar parameters. Then sets Attr.Style as follows:

Attr.Style = WS_CHILD I WS_VISIBLE I WS_GROUP I WS_TABSTOP I CBS_SORT I CBS_AUTOHSCROLL I WS_VSCROLL I style;

One of the following combo box style constants must be among the styles set in style: CBS_SIMPLE, CBS_DROPDOWN, CBS_DROPDOWNLIST, CBS_OWNERDRA WFIXED, or CBS_OWNERDRA WV ARIABLE.

TComboBox(TWindow* parent, int Id, WORD textLen, TModule* module

0);

Constructs a default combo box with the given parent window, control ID, and text length.

Public member functions

inline virtual int AddString(const char far* string);

Adds a string to an associated list part of a combo box. Returns the index of the string in the list. The first entry is at index zero. Returns a negative value if an error occurs.

inline void Clear();

Clears the text of the associated edit control.

inline virtual void ClearList();

Clears out all associated entries in the associated list.

inline virtual int DeleteString(int index);

Deletes the string at the passed index in the associated list part of a combo box. Returns a count of the entries remaining in the list or a negative value if an error occurs.

inline virtual int DirectoryList(UINT attrs, const char far* fileSpec);

Fills the combo box with file names from a specified directory.

inline virtual int FindString(const char far* find, int indexStart) const;

Searches for a match beginning at the passed Index. If a match is not found after the last string has been compared, the search continues from the beginning of the list until a match is found or until the list has been completely traversed. Returns the index of the first string in the associated list part of a combo box or a negative value if an error occurs.

inline virtual int GetCount() const;

Returns the number of entries in the associated list part of the combo box or a negative value if an error occurs.

GetDroppedControlRect inline void GetDroppedControlRect (TRect& Rect) const;

GetDroppedState

For combo boxes, gets the screen coordinates of the dropped down list box.

int GetEditSel(int &startPas, int &endPas);

Returns the starting and ending positions of the text selected in the associated edit control. Returns CB_ERR if the combo box has no edit control.

inline BOOL GetExtendedUI() canst;

Determines if the combo box has the extended user interface, which differs from the default user interface in the following ways:

• Displays the list box if the user clicks the static text field.

• Displays the list box if the user presses the -L. key.

• Disables scrolling in the static text field if the item list is not visible.

Returns TRUE if the combo box has the extended user interface; otherwise returns FALSE.
