   2
   3 wxAuiManager is the central class of the wxAUI class framework.
   4
   5 See also \helpref{wxAUI overview}{wxauioverview}.
   6
   7 wxAuiManager manages the panes associated with it
   8 for a particular wxFrame, using a pane's wxAuiPaneInfo information to
   9 determine each pane's docking and floating behavior. wxAuiManager
  10 uses wxWidgets' sizer mechanism to plan the layout of each frame. It
  11 uses a replaceable dock art class to do all drawing, so all drawing is
  12 localized in one area, and may be customized depending on an
  13 application's specific needs.
  14
  15 wxAuiManager works as follows: the programmer adds panes to the class,
  16 or makes changes to existing pane properties (dock position, floating
  17 state, show state, etc.). To apply these changes, wxAuiManager's
  18 Update() function is called. This batch processing can be used to avoid
  19 flicker, by modifying more than one pane at a time, and then "committing"
  20 all of the changes at once by calling Update().
  21
  22 Panes can be added quite easily:
  23
  24 \begin{verbatim}
  25 wxTextCtrl* text1 = new wxTextCtrl(this, -1);
  26 wxTextCtrl* text2 = new wxTextCtrl(this, -1);
  27 m_mgr.AddPane(text1, wxLEFT, wxT("Pane Caption"));
  28 m_mgr.AddPane(text2, wxBOTTOM, wxT("Pane Caption"));
  29 m_mgr.Update();
  30 \end{verbatim}
  31
  32 Later on, the positions can be modified easily. The following will float
  33 an existing pane in a tool window:
  34
  35 \begin{verbatim}
  36 m_mgr.GetPane(text1).Float();
  37 \end{verbatim}
  38
  39 \wxheading{Layers, Rows and Directions, Positions}
  40
  41 Inside wxAUI, the docking layout is figured out by checking several
  42 pane parameters. Four of these are important for determining where a
  43 pane will end up:
  44
  45 {\bf Direction:}
  46 Each docked pane has a direction, Top, Bottom, Left, Right, or
  47 Center. This is fairly self-explanatory. The pane will be placed in the
  48 location specified by this variable.
  49
  50 {\bf Position:}
  51 More than one pane can be placed inside of a dock. Imagine two panes
  52 being docked on the left side of a window. One pane can be placed over
  53 another. In proportionally managed docks, the pane position indicates
  54 its sequential position, starting with zero. So, in our scenario with
  55 two panes docked on the left side, the top pane in the dock would have
  56 position 0, and the second one would occupy position 1.
  57
  58 {\bf Row:}
  59 A row can allow for two docks to be placed next to each other. One of
  60 the most common places for this to happen is in the toolbar. Multiple
  61 toolbar rows are allowed, the first row being row 0, and the second
  62 row 1. Rows can also be used on vertically docked panes.
  63
  64 {\bf Layer:}
  65 A layer is akin to an onion. Layer 0 is the very center of the
  66 managed pane. Thus, if a pane is in layer 0, it will be closest to the
  67 center window (also sometimes known as the "content window").
  68 Increasing layers "swallow up" all layers of a lower value. This can
  69 look very similar to multiple rows, but is different because all panes
  70 in a lower level yield to panes in higher levels. The best way to
  71 understand layers is by running the wxAUI sample.

 125
 126 \func{}{wxAuiManager}{\param{wxWindow* }{managed\_wnd = NULL}, \param{unsigned int }{flags = wxAUI\_MGR\_DEFAULT}}
 127
 128 Constructor. \arg{frame} specifies the wxFrame which should be managed.
 129 \arg{flags}  specifies options which allow the frame management behavior
 130 to be modified.

 136 \membersection{wxAuiManager::AddPane}\label{wxauimanageraddpane}
 137
 138 \func{bool}{AddPane}{\param{wxWindow* }{window}, \param{const wxAuiPaneInfo\& }{pane\_info}}
 139
 140 \func{bool}{AddPane}{\param{wxWindow* }{window}, \param{int }{direction = wxLEFT}, \param{const wxString\& }{caption = wxEmptyString}}
 141
 142 \func{bool}{AddPane}{\param{wxWindow* }{window}, \param{const wxAuiPaneInfo\& }{pane\_info}, \param{const wxPoint\& }{drop\_pos}}
 143
 144
 145 AddPane() tells the frame manager to start managing a child window. There are several versions of this function. The first version allows the full spectrum of pane parameter possibilities. The second version is used for simpler user interfaces which do not require as much configuration.  The last version allows a drop position to be specified, which will determine where the pane will be added.
 146
 147 \membersection{wxAuiManager::DetachPane}\label{wxauimanagerdetachpane}
 148
 149 \func{bool}{DetachPane}{\param{wxWindow* }{window}}
 150
 151 Tells the wxAuiManager to stop managing the pane specified by window.
 152 The window, if in a floated frame, is reparented to the frame managed
 153 by wxAuiManager.
 154
 155 \membersection{wxAuiManager::GetAllPanes}\label{wxauimanagergetallpanes}
 156
 157 \func{wxAuiPaneInfoArray\&}{GetAllPanes}{\void}
 158
 159 Returns an array of all panes managed by the frame manager.
 160
 161 \membersection{wxAuiManager::GetArtProvider}\label{wxauimanagergetartprovider}
 162
 163 \constfunc{wxAuiDockArt*}{GetArtProvider}{\void}
 164
 165 Returns the current art provider being used.
 166
 167 See also: \helpref{wxAuiDockArt}{wxauidockart}.
 168
 169 \func{void}{GetDockSizeConstraint}{\param{double* }{widthpct}, \param{double* }{heightpct}}
 170
 171 Returns the current dock constraint values.  See SetDockSizeConstraint() for more information.
 172
 173 \membersection{wxAuiManager::GetFlags}\label{wxauimanagergetflags}
 174
 175 \constfunc{unsigned int}{GetFlags}{\void}
 176
 177 Returns the current manager's flags.
 178
 179 \membersection{wxAuiManager::GetManagedWindow}\label{wxauimanagergetmanagedwindow}
 180
 181 \constfunc{wxWindow*}{GetManagedWindow}{\void}
 182
 183 Returns the frame currently being managed by wxAuiManager.
 184
 185 \func{static wxAuiManager*}{GetManager}{\param{wxWindow* }{window}}
 186
 187 Calling this method will return the wxAuiManager for a given window.  The \arg{window} parameter should
 188 specify any child window or sub-child window of the frame or window managed by wxAuiManager.
 189 The \arg{window} parameter need not be managed by the manager itself, nor does it even need to be a child
 190 or sub-child of a managed window.  It must however be inside the window hierarchy underneath the managed
 191 window.
 192
 193 \membersection{wxAuiManager::GetPane}\label{wxauimanagergetpane}
 194
 195 \func{wxAuiPaneInfo\&}{GetPane}{\param{wxWindow* }{window}}
 196
 197 \func{wxAuiPaneInfo\&}{GetPane}{\param{const wxString\& }{name}}
 198
 199 {\it GetPane} is used to lookup a wxAuiPaneInfo object
 200 either by window pointer or by pane name, which acts as a unique id for
 201 a window pane. The returned wxAuiPaneInfo object may then be modified to
 202 change a pane's look, state or position. After one or more
 203 modifications to wxAuiPaneInfo, wxAuiManager::Update() should be called
 204 to commit the changes to the user interface. If the lookup failed
 205 (meaning the pane could not be found in the manager), a call to the
 206 returned wxAuiPaneInfo's IsOk() method will return false.
 207
 208 \membersection{wxAuiManager::HideHint}\label{wxauimanagerhidehint}
 209
 210 \func{void}{HideHint}{\void}
 211
 212 HideHint() hides any docking hint that may be visible.
 213
 214 \membersection{wxAuiManager::InsertPane}\label{wxauimanagerinsertpane}
 215
 216 \func{bool}{InsertPane}{\param{wxWindow* }{window}, \param{const wxAuiPaneInfo\& }{insert\_location}, \param{int }{insert\_level = wxAUI\_INSERT\_PANE}}
 217
 218 This method is used to insert either a previously unmanaged pane window
 219 into the frame manager, or to insert a currently managed pane somewhere
 220 else. {\it InsertPane} will push all panes, rows, or docks aside and
 221 insert the window into the position specified by \arg{insert\_location}.
 222 Because \arg{insert\_location} can specify either a pane, dock row, or dock
 223 layer, the \arg{insert\_level} parameter is used to disambiguate this. The
 224 parameter \arg{insert\_level} can take a value of wxAUI\_INSERT\_PANE, wxAUI\_INSERT\_ROW
 225 or wxAUI\_INSERT\_DOCK.
 226
 227 \membersection{wxAuiManager::LoadPaneInfo}\label{wxauimanagerloadpaneinfo}
 228
 229 \func{void}{LoadPaneInfo}{\param{wxString }{pane\_part}, \param{wxAuiPaneInfo\& }{pane}}
 230
 231 LoadPaneInfo() is similar to to LoadPerspective, with the exception that it only loads information about a single pane.  It is used in combination with SavePaneInfo().
 232
 233 \membersection{wxAuiManager::LoadPerspective}\label{wxauimanagerloadperspective}
 234
 235 \func{bool}{LoadPerspective}{\param{const wxString\& }{perspective}, \param{bool }{update = true}}
 236
 237 Loads a saved perspective. If update is true, wxAuiManager::Update()
 238 is automatically invoked, thus realizing the saved perspective on screen.
 239
 240 \membersection{wxAuiManager::ProcessDockResult}\label{wxauimanagerprocessdockresult}
 241
 242 \func{bool}{ProcessDockResult}{\param{wxAuiPaneInfo\& }{target}, \param{const wxAuiPaneInfo\& }{new\_pos}}
 243
 244 ProcessDockResult() is a protected member of the wxAUI layout manager.  It can be overridden by derived classes to provide custom docking calculations.
 245
 246 \membersection{wxAuiManager::SavePaneInfo}\label{wxauimanagersavepaneinfo}
 247
 248 \func{wxString}{SavePaneInfo}{\param{wxAuiPaneInfo\& }{pane}}
 249
 250 SavePaneInfo() is similar to SavePerspective, with the exception that it only saves information about a single pane.  It is used in combination with LoadPaneInfo().
 251
 252 \membersection{wxAuiManager::SavePerspective}\label{wxauimanagersaveperspective}
 253
 254 \func{wxString}{SavePerspective}{\void}
 255
 256 Saves the entire user interface layout into an encoded wxString, which
 257 can then be stored by the application (probably using wxConfig). When
 258 a perspective is restored using LoadPerspective(), the entire user
 259 interface will return to the state it was when the perspective was saved.
 260
 261 \membersection{wxAuiManager::SetArtProvider}\label{wxauimanagersetartprovider}
 262
 263 \func{void}{SetArtProvider}{\param{wxAuiDockArt* }{art\_provider}}
 264
 265 Instructs wxAuiManager to use art provider specified by parameter
 266 \arg{art\_provider} for all drawing calls. This allows plugable
 267 look-and-feel features. The previous art provider object, if any,
 268 will be deleted by wxAuiManager.
 269
 270 See also: \helpref{wxAuiDockArt}{wxauidockart}.
 271
 272 \func{void}{SetDockSizeConstraint}{\param{double }{widthpct}, \param{double }{heightpct}}
 273
 274 When a user creates a new dock by dragging a window into a docked position, often times the large size of the
 275 window will create a dock that is unwieldly large.  wxAuiManager by default limits the size of any
 276 new dock to 1/3 of the window size.  For horizontal docks, this would be 1/3 of the window height.  For
 277 vertical docks, 1/3 of the width.  Calling this function will adjust this constraint value.  The numbers
 278 must be between 0.0 and 1.0.  For instance, calling SetDockSizeContraint with 0.5, 0.5 will cause new
 279 docks to be limited to half of the size of the entire managed window.
 280
 281 \membersection{wxAuiManager::SetFlags}\label{wxauimanagersetflags}
 282
 283 \func{void}{SetFlags}{\param{unsigned int }{flags}}
 284
 285 This method is used to specify wxAuiManager's settings flags. \arg{flags}
 286 specifies options which allow the frame management behavior to be modified.
 287
 288 \membersection{wxAuiManager::SetManagedWindow}\label{wxauimanagersetmanagedwindow}
 289
 290 \func{void}{SetManagedWindow}{\param{wxWindow* }{managed\_wnd}}
 291
 292 Called to specify the frame or window which is to be managed by wxAuiManager.  Frame management is not restricted to just frames.  Child windows or custom controls are also allowed.
 293
 294 \membersection{wxAuiManager::ShowHint}\label{wxauimanagershowhint}
 295
 296 \func{void}{ShowHint}{\param{const wxRect\& }{rect}}
 297
 298 This function is used by controls to explicitly show a hint window at the specified rectangle.  It is rarely called, and is mostly used by controls implementing custom pane drag/drop behaviour.  The specified rectangle should be in screen coordinates.
 299
 300 \membersection{wxAuiManager::UnInit}\label{wxauimanageruninit}
 301
 302 \func{void}{UnInit}{\void}
 303
 304 Uninitializes the framework and should be called before a managed frame or window is destroyed. UnInit() is usually called in the managed wxFrame's destructor.  It is necessary to call this function before the managed frame or window is destroyed, otherwise the manager cannot remove its custom event handlers from a window.
 305
 306 \membersection{wxAuiManager::Update}\label{wxauimanagerupdate}
 307
 308 \func{void}{Update}{\void}
 309
 310 This method is called after any number of changes are
 311 made to any of the managed panes. Update() must be invoked after
 312 AddPane() or InsertPane() are called in order to "realize" or "commit"
 313 the changes. In addition, any number of changes may be made to
 314 wxAuiPaneInfo structures (retrieved with wxAuiManager::GetPane), but to
 315 realize the changes, Update() must be called. This construction allows
 316 pane flicker to be avoided by updating the whole layout at one time.
 317
