Member Function Documentation

◆ About()

HRESULT About ( void  )

Displays the control's credits

Displays some information about this control and its author.

◆ Click()

HRESULT Click ( void  )

Clicks the frame by code

See also
_IFrameEvents::Click

◆ GetControlState()

HRESULT GetControlState ( [out, retval] ControlStateConstants pControlState)

Retrieves a bit field describing the control's state

Returns
A bit field of constants defined by the ControlStateConstants enumeration, that describe the control's state.
See also
ControlStateConstants

◆ LoadSettingsFromFile()

HRESULT LoadSettingsFromFile ( [in] BSTR  file,
[out, retval] VARIANT_BOOL *  pSucceeded 
)

Loads the control's settings from the specified file

Parameters
[in]fileThe file to read from.
Returns
True if the settings could be loaded; otherwise False.
See also
SaveSettingsToFile

◆ SaveSettingsToFile()

HRESULT SaveSettingsToFile ( [in] BSTR  file,
[out, retval] VARIANT_BOOL *  pSucceeded 
)

Saves the control's settings to the specified file

Parameters
[in]fileThe file to write to.
Returns
True if the settings could be saved; otherwise False.
See also
LoadSettingsFromFile

◆ FinishOLEDragDrop()

HRESULT FinishOLEDragDrop ( void  )

Finishes a pending drop operation

During a drag'n'drop operation the drag image is displayed until the OLEDragDrop event has been handled. This order is intended by Microsoft Windows. However, if a message box is displayed from within the OLEDragDrop event, or the drop operation cannot be performed asynchronously and takes a long time, it may be desirable to remove the drag image earlier.
This method will break the intended order and finish the drag'n'drop operation (including removal of the drag image) immediately.

Remarks
This method will fail if not called from the OLEDragDrop event handler or if no drag images are used.

◆ UseImprovedImageListSupport

VARIANT_BOOL UseImprovedImageListSupport
getsetproperty

Specifies whether the control uses code that makes usage of image lists easier

The Windows native button control supports assignment of an image list to display an icon on the button, but it requires the icon to be the first one in the image list. For this reason each button needs its own image list, so the more buttons with icons are used, the more image lists have to be created and managed. This leads to bloated code.
TimoSoft ButtonControls can work around this issue and allow the client application to specify the icons used by a button individually, so that all buttons can share the same image list. However, this feature slightly changes the control's behavior, so it must be activated explicitly to keep backward compatibility.
If this property is set to True, the work-around is activated; otherwise not.

Remarks
This property cannot be set at run-time.

hImageList, IconIndex

◆ UseSystemFont

VARIANT_BOOL UseSystemFont
getsetproperty

Specifies whether the control uses the system font

Retrieves or sets whether the control uses the MS Shell Dlg font (which is mapped to the system's default GUI font) or the font specified by the Font property. If set to True, the system font; otherwise the specified font is used.

◆ Version

BSTR Version
get
