_GUICtrlRichEdit_GetFont does not return an empty string for mixed fonts

Reported by: ILLBeBack Owned by: Jpm
Milestone: 3.3.9.22 Component: Standard UDFs
Version: 3.3.9.21 Severity: None
Keywords: _GUICtrlRichEdit_GetFont Cc:

Description

According to the doc, _GUICtrlRichEdit_GetFont should return an empty string when the selection contains mixed font. This makes sense, and is similar to what happens in VB for RichText. However, this is not what happens. Instead, the name of the font at the start of the selection is returned (depends on direction of selection).

The example script below will demonstrate this. When started, the 3 lines of text in the RichEdit box will be selected. Each line is a different font face. WIth all 3 lines selected, click the button to show the font face (in the label below the RichEdit) that is returned by _GUICtrlRichEdit_GetFont.


It also demonstrates a second issue, that being the inability to make another selection after _GUICtrlRichEdit_GetFont is used.

Note: The 2nd issue is related to the “invisible selection” issue reported as "Selection goes invisible after _GUICtrlRichEdit_GetFont".
