wxTreebookThis class is an extension of the Notebook class that allows a tree structured set of pages to be shown in a control. A classic example is a netscape preferences dialog that shows a tree of preference sections on the left and select section page on the right. To use the class simply create it and populate with pages using InsertPage, InsertSubPage, AddPage, AddSubPage. If your tree is no more than 1 level in depth then you could simply use AddPage and AddSubPage to sequentially populate your tree by adding at every step a page or a subpage to the end of the tree. Derived from
wxBookCtrlBase Include files <wx/treebook.h> Event handling To process input from a treebook control, use the following event handler macros to direct input to member functions that take a wxTreebookEvent argument.

wxTreebook::wxTreebook
wxTreebook::wxTreebookwxTreebook() Default constructor. wxTreebook( wxWindow* parent, wxWindowID id, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxBK_DEFAULT, const wxString& name = wxEmptyString) Creates an empty TreeBook control. Parameters parent
id
pos
size
style
name
wxTreebook::~wxTreebook~wxTreebook() Destroys the wxTreebook object. Also deletes all the pages owned by the control (inserted previously into it).
wxTreebook::AddPagebool AddPage( wxWindow* page, const wxString& text, bool bSelect = false, int imageId = wxNOT_FOUND) Adds a new page. The page is placed at the topmost level after all other pages. NULL could be specified for page to create an empty page.
wxTreebook::AddSubPagebool AddSubPage(wxWindow* page, const wxString& text, bool bSelect = false, int imageId = wxNOT_FOUND) Adds a new child-page to the last top-level page. NULL could be specified for page to create an empty page.
wxTreebook::AssignImageListvoid AssignImageList(wxImageList* imageList) Sets the image list for the page control and takes ownership of the list. See also
wxTreebook::ChangeSelectionint ChangeSelection(size_t page) Changes the selection for the given page, returning the previous selection. The call to this function does not generate the page changing events. This is the only difference with SetSelection. See this topic for more info.
wxTreebook::CollapseNodebool CollapseNode(size_t pageId) Shortcut for ExpandNode(pageId, false).
wxTreebook::Createbool Create(wxWindow* parent, wxWindowID id, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxBK_DEFAULT, const wxString& name = wxEmptyString) Creates a treebook control. See wxTreebook::wxTreebook for the description of the parameters.
wxTreebook::DeleteAllPagesbool DeleteAllPages() Deletes all pages inserted into the treebook. No event is generated.
wxTreebook::DeletePagebool DeletePage(size_t pagePos) Deletes the page at the specified position and all its children. Could trigger page selection change in a case when selected page is removed. In that case its parent is selected (or the next page if no parent).
wxTreebook::ExpandNodebool ExpandNode(size_t pageId, bool expand = true) Expands (collapses) the pageId node. Returns the previous state. May generate page changing events (if selected page is under the collapsed branch, then its parent is autoselected).
wxTreebook::GetPageImageint GetPageImage(size_t n) const Returns the image index for the given page.
wxTreebook::GetPageParentint GetPageParent(size_t page) const Returns the parent page of the given one or wxNOT_FOUND if this is a top-level page.
wxTreebook::GetPageTextwxString GetPageText(size_t n) const Returns the string for the given page.
wxTreebook::GetSelectionint GetSelection() const Returns the currently selected page, or wxNOT_FOUND if none was selected. Note that this method may return either the previously or newly selected page when called from the EVT_TREEBOOK_PAGE_CHANGED handler depending on the platform and so wxTreebookEvent::GetSelection should be used instead in this case.
wxTreebook::InsertPagebool InsertPage(size_t pagePos, wxWindow* page, const wxString& text, bool bSelect = false, int imageId = wxNOT_FOUND) Inserts a new page just before the page indicated by pagePos. The new page is placed before pagePos page and on the same level. NULL could be specified for page to create an empty page.
wxTreebook::InsertSubPagebool InsertSubPage(size_t pagePos, wxWindow* page, const wxString& text, bool bSelect = false, int imageId = wxNOT_FOUND) Inserts a sub page under the specified page. NULL could be specified for page to create an empty page.
wxTreebook::IsNodeExpandedbool IsNodeExpanded(size_t pageId) const Gets the pagePos page state -- whether it is expanded or collapsed
wxTreebook::SetImageListvoid SetImageList(wxImageList* imageList) Sets the image list for the page control. It does not take ownership of the image list, you must delete it yourself. See also
wxTreebook::SetPageImagebool SetPageImage(size_t page, int imageId) Sets the image index for the given page. ImageId is an index into the image list which was set with SetImageList.
wxTreebook::SetPageTextbool SetPageText(size_t page, const wxString& text) Sets the text for the given page.
wxTreebook::SetSelectionint SetSelection(size_t n) Sets the selection for the given page, returning the previous selection. The call to this function generates the page changing events. This function is deprecated and should not be used in new code. Please use the ChangeSelection function instead. See also |
