The ITextControl class is an abstract base class for all text control window classes. It provides functions that manipulate text strings.
ITextControl is not the class corresponding to a text widget. If you are looking for a class for a text widget, see IEntryField and IMultiLineEdit.
Constructors & DestructorBecause this class is an abstract base class, you cannot directly construct objects of this class. The only way to construct objects of this class is from a derived class. To enforce this, the only constructor we provide for this class is protected. You can destruct objects of this class.
![]() |
protected:
ITextControl()
Derived classes use this protected constructor to create objects of this class.
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
Clipboard OperationsUse these members to interface with the clipboard.
![]() |
public:
static bool clipboardHasTextFormat()
Returns true if the clipboard is in text format.
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
If one of the registered formats for the clipboard data is of type "STRING," this function returns true.
Layout SupportLayout-support members are overrides that supply information used by the canvas classes to provide dialog-like behavior.
![]() |
public:
virtual ITextControl& setLayoutDistorted( unsigned long layoutAttributeOn, unsigned long layoutAttributeOff )
Processes a font change like a minimum size change. This is a virtual override of setLayoutDistorted.
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
Notification MembersUse these members to identify and enable notifications sent to observer objects.
![]() |
public:
static INotificationId const textId
Notification identifier provided to observers when the text of a text control window changes.
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
Text ProcessingUse these members to manage the text. You can query and set the text as well as query the length of the text for objects of this class.
![]() |
Sets the control window's text.
If the setText member function is used to set the text in an IComboBox constructed with the readOnlyDropDown style, non-null text specified must already exist in the combo box list. The item matching the new text will be selected. If the new text specified is the null string, all items in the list will be deselected.
public:
virtual ITextControl& setText(const IResourceId& text)
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
public:
virtual ITextControl& setText(const char* text)
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
![]() |
public:
virtual IString text() const
Returns the control window's text.
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
![]() |
public:
virtual unsigned long textLength() const
Returns the current length of the control window's text in bytes.
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
Window PaintingUse these members to update the window.
![]() |
public:
virtual ISize displaySize(const char* text = 0) const
Returns the width and height of the rectangle enclosing the string. If you do not specify a string, the size needed to contain the current text is returned.
| IAccessError | The operating system's request to query the size of the text box failed. |
| Windows | OS/2 | AIX |
| Yes | Yes | Yes |
This member uses the underlying widget's current font list. It supports multiple-byte character sets but not sheared or rotated strings.
This function uses the font attribute of the presentation space, including a sheared or rotated string. This function also supports double-byte character set (DBCS) characters.
