wx.richtext.SymbolPickerDialog¶

wx.richtext.SymbolPickerDialog presents the user with a choice of fonts and a grid of available characters.

This modal dialog provides the application with a selected symbol and optional font selection.

Although this dialog is contained in the rich text library, the dialog is generic and can be used in other contexts.

To use the dialog, pass a default symbol specified as a string, an initial font name, and a current font name. The difference between the initial font and current font is that the initial font determines what the font control will be set to when the dialog shows - an empty string will show the selection normal text. The current font, on the other hand, is used by the dialog to determine what font to display the characters in, even when no initial font is selected. This allows the user (and application) to distinguish between inserting a symbol in the current font, and inserting it with a specified font.

When the dialog is dismissed, the application can get the selected symbol with wx.richtext.SymbolPickerDialog.GetSymbol and test whether a font was specified with wx.richtext.SymbolPickerDialog.UseNormalFont ,fetching the specified font with wx.richtext.SymbolPickerDialog.GetFontName .

Here’s a realistic example, inserting the supplied symbol into a rich text control in either the current font or specified font.

ctrl = self.FindWindow(ID_RICHTEXT_CTRL)

attr = wx.TextAttr()
attr.SetFlags(wx.TEXT_ATTR_FONT)
ctrl.GetStyle(ctrl.GetInsertionPoint(), attr)

currentFontName = ''
if (attr.HasFont() and attr.GetFont().IsOk()):
    currentFontName = attr.GetFont().GetFaceName()

# Don't set the initial font in the dialog (so the user is choosing
# 'normal text', i.e. the current font) but do tell the dialog
# what 'normal text' is.

dlg = wx.richtext.SymbolPickerDialog("*", '', currentFontName, self)

if dlg.ShowModal() == wx.ID_OK:

    if dlg.HasSelection():

        insertionPoint = ctrl.GetInsertionPoint()

        ctrl.WriteText(dlg.GetSymbol())

        if not dlg.UseNormalFont():

            font = attr.GetFont()
            font.SetFaceName(dlg.GetFontName())
            attr.SetFont(font)
            ctrl.SetStyle(insertionPoint, insertionPoint+1, attr)
