Detailed Description

GUI editors, e.g., wxFormBuilder, typically allow users to lay out instances of controls.

However, wxVListBox is an abstract class, so a GUI editor can only create instances of a subclass of wxVListBox. Rather than require every GUI editor to repeat the work of subclassing wxVListBox for GUI editing, and because the user's intended subclass will not exist in GUI editors, provide a class that GUI editors can use. Also, the wxVListBoxXmlHandler can create instances of this class when in wxXRC_NO_SUBCLASSING mode;

Additional Inherited Members

- Protected Member Functions inherited from wxVListBox
virtual void OnDrawItem (wxDC &dc, const wxRect &rect, size_t n) const =0
 The derived class must implement this function to actually draw the item with the given index on the provided DC. More...
 
virtual void OnDrawBackground (wxDC &dc, const wxRect &rect, size_t n) const

- Protected Member Functions inherited from wxVarVScrollHelper
virtual void OnGetRowsHeightHint (size_t rowMin, size_t rowMax) const
 This function doesn't have to be overridden but it may be useful to do so if calculating the rows' sizes is a relatively expensive operation as it gives your code a chance to calculate several of them at once and cache the result if necessary. More...
 
virtual wxCoord EstimateTotalHeight () const
 This class forwards calls from EstimateTotalSize() to this function so derived classes can override either just the height or the width estimation, or just estimate both differently if desired in any wxHVScrolledWindow derived class. More...
 
virtual wxCoord OnGetRowHeight (size_t row) const =0
 This function must be overridden in the derived class, and should return the height of the given row in pixels. More...

Constructor & Destructor Documentation

◆ wxXRCPreviewVListBox() [1/2]

wxXRCPreviewVListBox::wxXRCPreviewVListBox ( )

Default constructor, you must call Create() later.

◆ wxXRCPreviewVListBox() [2/2]

wxXRCPreviewVListBox::wxXRCPreviewVListBox ( wxWindow parent,
wxWindowID  id = wxID_ANY,
const wxPoint pos = wxDefaultPosition,
const wxSize size = wxDefaultSize,
long  style = 0,
const wxString name = wxXRCPreviewVListBoxNameStr 
)

Normal constructor which calls Create() internally.

Member Function Documentation

◆ Create()

bool wxXRCPreviewVListBox::Create ( wxWindow parent,
wxWindowID  id = wxID_ANY,
const wxPoint pos = wxDefaultPosition,
const wxSize size = wxDefaultSize,
long  style = 0,
const wxString name = wxXRCPreviewVListBoxNameStr 
)

Creates the control.

To finish creating it you also should call SetItemCount() to let it know about the number of items it contains.

The only special style which may be used with wxXRCPreviewVListBox is wxLB_MULTIPLE which indicates that the listbox should support multiple selection.

Returns
true on success or false if the control couldn't be created.
