Supported special attributes:

• PG_DIALOG_TITLE: Sets a specific title for the file dialog (since 3.1.3).

• PG_FILE_DIALOG_STYLE: Sets a specific wx.FileDialog style for the file dialog.

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

files…” is default. - PG_FILE_SHOW_FULL_PATH: Default True. When False, only the file name is shown (i.e. drive and directory are hidden). - PG_FILE_SHOW_RELATIVE_PATH: If set, then the filename is shown relative to the given path string. - PG_FILE_INITIAL_PATH: Sets the initial path of where to look for files.

## Methods Summary¶

 __init__ OnCustomPaint Override to paint an image in front of the property value text or drop-down list item (but only if wx.propgrid.PGProperty.OnMeasureImage is overridden as well). OnMeasureImage Returns size of the custom painted image in front of property. OnSetValue This virtual function is called after m_value has been set.

## Class API¶

class wx.propgrid.ImageFileProperty(FileProperty)

Possible constructors:

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


Property representing image file(name).

### Methods¶

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

• name (string) –

• value (string) –

OnCustomPaint(self, dc, rect, paintdata)

Override to paint an image in front of the property value text or drop-down list item (but only if wx.propgrid.PGProperty.OnMeasureImage is overridden as well).

If property’s OnMeasureImage returns size that has height != 0 but less than row height ( < 0 has special meanings), wx.propgrid.PropertyGrid calls this method to draw a custom image in a limited area in front of the editor control or value text/graphics, and if control has drop-down list, then the image is drawn there as well (even in the case OnMeasureImage returned higher height than row height).

NOTE: Following applies when OnMeasureImage returns a “flexible” height ( using PG_FLEXIBLE_SIZE(W,H) macro), which implies variable height items: If (rect.x+rect.width) is < 0, then this is a measure item call, which means that dc is invalid and only thing that should be done is to set paintdata.m_drawnHeight to the height of the image of item at index paintdata.m_choiceItem. This call may be done even as often as once every drop-down popup show.

Parameters

Note

• You can actually exceed rect width, but if you do so then paintdata.m_drawnWidth must be set to the full width drawn in pixels.

• Due to technical reasons, rect’s height will be default even if custom height was reported during measure call.

• Brush is guaranteed to be default background colour. It has been already used to clear the background of area being painted. It can be modified.

• Pen is guaranteed to be 1-wide ‘black’ (or whatever is the proper colour) pen for drawing framing rectangle. It can be changed as well.

OnMeasureImage(self, item)

Returns size of the custom painted image in front of property.

This method must be overridden to return non-default value if OnCustomPaint is to be called.

Parameters

item (int) – Normally -1, but can be an index to the property’s list of items.

Return type

Size

Note

• Default behaviour is to return wx.Size, which means no image.

• Default image width or height is indicated with dimension -1.

• You can also return PG_DEFAULT_IMAGE_SIZE which equals DefaultSize.

OnSetValue(self)

This virtual function is called after m_value has been set.

Note

• If m_value was set to Null variant (i.e. 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.
