phoenix_title wx.propgrid.FileProperty

Like wx.propgrid.LongStringProperty, but the button triggers file selector instead.

Supported special attributes:

  • “Wildcard”: Sets wildcard (see wx.FileDialog for format details), “All

files...” is default. - “ShowFullPath”: Default 1. When 0, only the file name is shown (i.e. drive and directory are hidden). - “ShowRelativePath”: If set, then the filename is shown relative to the given path string. - “InitialPath”: Sets the initial path of where to look for files. - “DialogTitle”: Sets a specific title for the dir dialog.

class wx.propgrid.FileProperty(PGProperty)

Possible constructors:

FileProperty(label=PG_LABEL, name=PG_LABEL, value="")

Like LongStringProperty, but the button triggers file selector instead.


Methods


__init__(self, label=PG_LABEL, name=PG_LABEL, value="")
Parameters:
  • label (string) –
  • name (string) –
  • value (string) –

DoGetValidator(self)

Returns pointer to the wx.Validator that should be used with the editor of this property (None for no validator).

Setting validator explicitly via SetPropertyValidator will override this.

In most situations, code like this should work well (macros are used to maintain one actual validator instance, so on the second call the function exits within the first macro):

class MyPropertyClass(wx.propgrid.FileProperty):
    ...
    def DoGetValidator(self):
        validator = MyValidator(...)

        ... prepare validator...

        return validator
Return type:Validator

Note

You can get common filename validator by returning wx.propgrid.FileProperty.GetClassValidator . wx.propgrid.DirProperty, for example, uses it.


DoSetAttribute(self, name, value)

Reimplement this member function to add special handling for attributes of this property.

Parameters:
  • name (string) –
  • value (PGVariant) –
Return type:

bool
Returns:

Return False to have the attribute automatically stored in m_attributes. Default implementation simply does that and nothing else.

Note

To actually set property attribute values from the application, use wx.propgrid.PGProperty.SetAttribute instead.


static GetClassValidator()
Return type:Validator

GetEditorDialog(self)

Returns instance of a new wx.propgrid.PGEditorDialogAdapter instance, which is used when user presses the (optional) button next to the editor control;.

Default implementation returns None (ie. no action is generated when button is pressed).

Return type: wx.propgrid.PGEditorDialogAdapter

GetFileName(self)

Returns filename to file represented by current value.

Return type:string

OnSetValue(self)

This virtual function is called after m_value has been set.

Note

  • If m_value was set to Null variant (ie. unspecified value), OnSetValue will not be called.
  • m_value may be of any variant type. Typically properties internally support only one variant type, and as such OnSetValue provides a good opportunity to convert supported values into internal type.
  • Default implementation does nothing.

StringToValue(self, variant, text, argFlags=0)

Converts text into Variant value appropriate for this property.

Parameters:
  • variant (PGVariant) – On function entry this is the old value (should not be NullVariant in normal cases). Translated value must be assigned back to it.
  • text (string) – Text to be translated into variant.
  • argFlags (int) – If wx.propgrid.PG_FULL_VALUE is set, returns complete, storable value instead of displayable one (they may be different). If wx.propgrid.PG_COMPOSITE_FRAGMENT is set, text is interpreted as a part of composite property string value (as generated by ValueToString called with this same flag).
Return type:

bool

You might want to take into account that m_value is Null variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).

Returns:Returns True if resulting Variant value was different.

Note

Default implementation converts semicolon delimited tokens into child values. Only works for properties with children.


ValueToString(self, value, argFlags=0)

Converts property value into a text representation.

Parameters:
  • value (PGVariant) – Value to be converted.
  • argFlags (int) – If 0 (default value), then displayed string is returned. If wx.propgrid.PG_FULL_VALUE is set, returns complete, storable string value instead of displayable. If wx.propgrid.PG_EDITABLE_VALUE is set, returns string value that must be editable in textctrl. If wx.propgrid.PG_COMPOSITE_FRAGMENT is set, returns text that is appropriate to display as a part of string property’s composite text representation.
Return type:

string

Note

Default implementation calls GenerateComposedValue .
