Like wx.propgrid.LongStringProperty, but the button triggers file selector instead.
Supported special attributes:
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.
__init__ |
|
DoGetValidator |
Returns pointer to the wx.Validator that should be used with the editor of this property (None for no validator). |
DoSetAttribute |
Reimplement this member function to add special handling for attributes of this property. |
GetClassValidator |
|
GetEditorDialog |
Returns instance of a new wx.propgrid.PGEditorDialogAdapter instance, which is used when user presses the (optional) button next to the editor control;. |
GetFileName |
Returns filename to file represented by current value. |
OnSetValue |
This virtual function is called after m_value has been set. |
StringToValue |
Converts text into Variant value appropriate for this property. |
ValueToString |
Converts property value into a text representation. |
wx.propgrid.
FileProperty
(PGProperty)¶Possible constructors:
FileProperty(label=PG_LABEL, name=PG_LABEL, value="")
Like LongStringProperty, but the button triggers file selector instead.
__init__
(self, label=PG_LABEL, name=PG_LABEL, value="")¶Parameters: |
|
---|
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: |
|
---|---|
Return type: | bool |
Returns: | Return |
Note
To actually set property attribute values from the application, use wx.propgrid.PGProperty.SetAttribute
instead.
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
OnSetValue
will not be called.OnSetValue
provides a good opportunity to convert supported values into internal type.StringToValue
(self, variant, text, argFlags=0)¶Converts text into Variant value appropriate for this property.
Parameters: |
|
---|---|
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: |
|
---|---|
Return type: |
|
Note
Default implementation calls GenerateComposedValue
.
