The FoldPanelBar is a class which can maintain a list of collapsable panels. Once a panel is collapsed, only it's caption bar is visible to the user. This will provide more space for the other panels, or allow the user to close panels which are not used often to get the most out of the work area.

This control is easy to use. Simply create it as a child for a panel or sash window, and populate panels with AddFoldPanel. Then use the AddFoldPanelWindow to add wx.Window derived controls to the current fold panel. Use AddFoldPanelSeparator to put separators between the groups of controls that need a visual separator to group them together. After all is constructed, the user can fold the panels by doubleclicking on the bar or single click on the arrow, which will indicate the collapsed or expanded state.

Instance Method Details

__init__(self, parent, id=-1, pos=wx.Point(-1, -1), size=wx.Size(-1, -1), style=2621440, extraStyle=0)
(Constructor)

Default Class Constructor.

Overrides:
wx.Panel.__init__

AddFoldPanel(self, caption='', collapsed=False, foldIcons=None, cbstyle=<wx.lib.agw.foldpanelbar.CaptionBarStyle instance at 0x1c...)

Adds a fold panel to the list of panels.

If the flag collapsed is set to True, the panel is collapsed initially. The FoldPanel item which is returned, can be used as a reference to perform actions upon the fold panel like collapsing it, expanding it, or deleting it from the list.

Use this foldpanel to add windows to it. Please consult AddFoldPanelWindow and AddFoldPanelSeparator to know how to add items derived from wx.Window to the panels.

AddFoldPanelSeparator(self, panel, colour=wx.Colour(), Spacing=8, leftSpacing=2, rightSpacing=2)

Adds a separator line to the current FoldPanel.

The seperator is a simple line which is drawn and is no real component. It can be used to separate groups of controls which belong to each other. The colour is adjustable, and it takes the same Spacing, leftSpacing and rightSpacing as AddFoldPanelWindow.

AddFoldPanelWindow(self, panel, window, flags=1, Spacing=8, leftSpacing=2, rightSpacing=2)

Adds a wx.Window derived instance to the referenced FoldPanel.

IMPORTANT: Make the window be a child of the FoldPanel. See example that follows. The flags to be used are:

  • FPB_ALIGN_WIDTH: Which means the wxWindow to be added will be aligned to fit the width of the FoldPanel when it is resized. Very handy for sizer items, buttons and text boxes.
  • FPB_ALIGN_LEFT: Aligns left instead of fitting the width of the child window to be added. Use either this one or FPB_ALIGN_WIDTH.

The wx.Window to be added can be slightly indented from left and right so it is more visibly placed in the FoldPanel. Use Spacing > 0 to give the control an y offset from the previous wx.Window added, use leftSpacing to give it a slight indent from the left, and rightSpacing also reserves a little space on the right so the wxWindow can be properly placed in the FoldPanel.

The following example adds a FoldPanel to the FoldPanelBar and adds two wx.Window derived controls to the FoldPanel:

# create the FoldPanelBar
>>> m_pnl = FoldPanelBar(self, wx.ID_ANY, wx.DefaultPosition,
                         wx.DefaultSize, FPB_DEFAULT_STYLE,
                         FPB_COLLAPSE_TO_BOTTOM)

# add a foldpanel to the control. "Test me" is the caption and it is
# initially not collapsed.
>>> item = m_pnl.AddFoldPanel("Test me", False)

# now add a button to the fold panel. Mind that the button should be
# made child of the FoldPanel and not of the main form.
>>> m_pnl.AddFoldPanelWindow(item, wx.Button(item, ID_COLLAPSEME,
                            "Collapse Me"))

# add a separator between the two controls. This is purely a visual
# line that can have a certain color and also the indents and width
# aligning like a control.
>>> m_pnl.AddFoldPanelSeparator(item)

# now add a text ctrl. Also very easy. Align this on width so that
# when the control gets wider the text control also sizes along.
>>> m_pnl.AddFoldPanelWindow(item, wx.TextCtrl(item, wx.ID_ANY, "Comment"),
                             FPB_ALIGN_WIDTH, FPB_DEFAULT_SPACING, 20)

ApplyCaptionStyle(self, foldpanel, cbstyle)

Sets the style of the caption bar (CaptionBar) of the FoldPanel.

The changes are applied immediately. All styles not set in the CaptionBarStyle class are not applied. Use the CaptionBar reference to indicate what captionbar you want to apply the style to. To apply one style to all CaptionBar items, use ApplyCaptionStyleAll

ApplyCaptionStyleAll(self, cbstyle)

Sets the style of all the caption bars of the FoldPanel.

The changes are applied immediately.

Collapse(self, foldpanel)

Collapses the given FoldPanel reference, and updates the foldpanel bar.

In the FPB_COLLAPSE_TO_BOTTOM style, all collapsed captions are put at the bottom of the control. In the normal mode, they stay where they are.

Expand(self, foldpanel)

Expands the given FoldPanel reference, and updates the foldpanel bar.

In the FPB_COLLAPSE_TO_BOTTOM style, they will be removed from the bottom and the order where the panel originally was placed is restored.

GetCaptionStyle(self, foldpanel)

Returns the currently used caption style for the FoldPanel.

It is returned as a CaptionBarStyle class. After modifying it, it can be set again.

GetCount(self)

Returns the number of panels in the FoldPanelBar.

GetFoldPanel(self, item)

Returns the panel associated with the index "item".

See the example at the bottom of the module, especially the events for the "Collapse Me" and "Expand Me" buttons.

GetPanelsLength(self, collapsed, expanded)

Returns the length of the panels that are expanded and collapsed.

This is useful to determine quickly what size is used to display, and what is left at the bottom (right) to align the collapsed panels.

IsVertical(self)

Returns whether the CaptionBar has default orientation or not.

Default is vertical.

OnPressCaption(self, event)

Handles the EVT_CAPTIONBAR event in the FoldPanelBar.

OnSizePanel(self, event)

Handles the EVT_SIZE event for the FoldPanelBar.

RedisplayFoldPanelItems(self)

Resizes the fold panels so they match the width.

RefreshPanelsFrom(self, item)

Refreshes all the panels from given index down to last one.

RepositionCollapsedToBottom(self)

Repositions all the collapsed panels to the bottom.

When it is not possible to align them to the bottom, stick them behind the visible panels. The Rect holds the slack area left between last repositioned panel and the bottom panels. This needs to get a refresh.
