The IBitmapControl class creates and manages a window to display a bitmap image. You can add text to the window by using the inherited setText functions.
You can construct and destruct objects of the IBitmapControl class. You cannot copy or assign IBitmapControl objects because both the copy constructor and the assignment operator are private functions.

Use these style members to provide valid styles for IBitmapControl::setDefaultStyle and for the constructor of the IBitmapControl class.
![]() |
public:
virtual unsigned long convertToGUIStyle( const IBitFlag& style, bool extendedOnly = false ) const
Converts a style object into a value appropriate for the presentation system. The default action is to return the base GUI styles for the platform. Extended styles, those defined by the application and the Open Class Library, are returned if you set extendedOnly to true.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
![]() |
public:
static Style defaultStyle()
Returns the default style. This style is classDefaultStyle unless you have changed it using setDefaultStyle.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
![]() |
public:
static void setDefaultStyle(const Style& style)
Sets the default style for all subsequent bitmap controls.
This member function is not thread safe. In a multithreaded application, it should only be called when a conflict is not possible. A conflict can arise if you set the default style on one thread at the same time that it is being queried on another. In this situation, the query would take place while the style is in an unknown state.
When you create a window class and do not specifically specify window styles in the constructor, the Open Class Library queries the default style. Therefore, the only safe place to call this member function is when no other application threads that create windows are active.
Another way to avoid a conflict in a multithreaded application is to specifically specify window styles on window construction, rather than calling this member function.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
![]() |
public:
static const Style classDefaultStyle
Returns the original default style for this class, which is IWindow::visible | IBitmapControl::sizeImageToWindow.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
![]() |
public:
static const Style sizeImageToWindow
Use this style to control the automatic stretching or shrinking of the graphical image to fit the window. If you set this style, the image is resized to cover the face of the window. If you do not set this style, the image is rendered in the center of the window without resizing. If the image is larger that the window, it is clipped at the boundaries of the window label area.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
![]() |
public:
static const Style sizeWindowToImage
Use this style to cause the window to be automatically resized to fit the image when you set a new image. The automatic resizing only occurs when a new image is set, such as during construction of the window or with the setBitmap function. Note that if there is text set in the window, the window is sized to accommodate the larger of the text and the image.
This style does not affect the behavior of the window if you use the sizeTo function after setting the image. You can use the sizeImageToWindow style to control automatic stretching or shrinking of the image. You can also set an IAlignmentAttribute for the window to control automatic resizing of the window by canvas classes such as IMultiCellCanvas.
Windows | OS/2 | AIX |
Yes | Yes | Yes |
Use these members to set the size and position of windows.
![]() |
public:
virtual IBitmapControl& moveSizeTo( const IRectangle& rectangle )
Changes the position and size of the window.
