phoenix_title wx.adv.BannerWindow

A simple banner window showing either a bitmap or text.

Banner windows can be used to present some overview of the current window contents to the user in an aesthetically pleasant way. They are typically positioned along the left or top edge of the window (although this class also supports right- and bottom-aligned banners) and show either a bitmap with a logo or a few lines of text on a gradient-filled background.

Using this class is very simple, e.g.:

class MyFrame(wx.Frame):

    def __init__(self, parent):

        # ... create the frame itself ...
        wx.Frame.__init__(self, parent)

        # Create and initialize the banner.
        banner = wx.adv.BannerWindow(self, wx.TOP)
        banner.SetText("Welcome to my wonderful program",
                       "  Before doing anything else, you need to connect to "
                       "the online server.\n"
                       "  Please enter your credentials in the controls below.")

        # And position it along the left edge of the window.
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(banner, wx.SizerFlags().Expand())

        # ... add the rest of the window contents to the same sizer ...

        self.SetSizerAndFit(sizer)

This class is currently implemented generically and so looks the same under all platforms.

New in version 2.9.3.

class wx.adv.BannerWindow(Window)

Possible constructors:

BannerWindow()

BannerWindow(parent, winid=ID_ANY, dir=LEFT, pos=DefaultPosition,
             size=DefaultSize, style=0, name=BannerWindowNameStr)

A simple banner window showing either a bitmap or text.


Methods

__init__(self, *args, **kw)

overload Overloaded Implementations:



__init__ (self)

Default constructor, use Create later.

This constructor is only used for two-step creation, if possible, prefer using the constructor below directly instead of using this one and calling Create later.



__init__ (self, parent, winid=ID_ANY, dir=LEFT, pos=DefaultPosition, size=DefaultSize, style=0, name=BannerWindowNameStr)

Full constructor provided for consistency with the other classes only.

Prefer to use the shorter constructor documented above. You should rarely, if ever, need to use non-default values for any other parameters: as the banner window doesn’t generate any events, its identifier is not particularly useful; its position and size will be almost always managed by the containing sizer and it doesn’t have any specific styles. So only the parent and the banner direction need to be specified.

Parameters





Create(self, parent, winid=ID_ANY, dir=LEFT, pos=DefaultPosition, size=DefaultSize, style=0, name=BannerWindowNameStr)

Really create the banner window for the objects created using the default constructor.

It’s an error to call Create for the objects created using non-default constructor.

Parameters

SetBitmap(self, bmp)

Provide the bitmap to use as background.

Notice that ideally the bitmap should be big enough to always cover the entire banner, e.g. for a horizontal banner with wx.TOP style its width should be bigger than any reasonable window size. Otherwise the bitmap is extended to cover the entire window area with a solid colour taken from the bitmap pixel on the edge in which direction the extension occurs so all bitmap pixels on this edge (top for wx.LEFT, right for wx.TOP and wx.BOTTOM and bottom for wx.RIGHT) should have the same colour to avoid jarring discontinuity.

If, on the other hand, the bitmap is bigger than the window size, then it is truncated. For wx.LEFT orientation the bitmap is truncated from the top, for wx.TOP and wx.BOTTOM – from the right and for wx.RIGHT – from the bottom, so put the most important part of the bitmap information in the opposite direction where it will never be truncated.

If no valid background bitmap is specified, the banner draws gradient background but if a valid bitmap is given here, the gradient is not draw and the start and end colours specified for it are ignored.

Parameters

bmp (wx.Bitmap) – Bitmap to use as background. May be invalid to indicate that no background bitmap should be used.



SetGradient(self, start, end)

Set the colours between which the gradient runs.

The gradient colours are ignored if SetBitmap is used.

Parameters


SetText(self, title, message)

Set the text to display.

This is mutually exclusive with SetBitmap .

Title is rendered in bold and should be single line, message can have multiple lines but is not wrapped automatically, include explicit line breaks in the string if you want to have multiple lines.

Parameters
  • title (string) –

  • message (string) –
