What red color means?

[ghost]

Some GUI elements are highlighted with red color. Is it just a decoration or a warning that something is wrong?

Any screenshot?

There is certain colorification to help identify filter/connection types

// filter colors
const COLORREF RenderParameters::color_filter_border_light = RGB(255, 255, 255);
const COLORREF RenderParameters::color_filter_border_dark = RGB(128, 128, 128);
const COLORREF RenderParameters::color_filter_type[4] = {
    RGB(192,192,192), // Filter::FILTER_UNKNOWN
    RGB(192,192,255), // Filter::FILTER_STANDARD
    RGB(255,128,0), // Filter::FILTER_WDM
    RGB(0,192,64)   // Filter::FILTER_DMO
};

const COLORREF RenderParameters::color_connection_break = RGB(192,0,0);
const COLORREF RenderParameters::color_connection_type[6] = {
    RGB(255,0,128),     // PIN_CONNECTION_TYPE_OTHER
    RGB(0,0,0),         // PIN_CONNECTION_TYPE_STREAM
    RGB(0,128,128),     // PIN_CONNECTION_TYPE_AUDIO
    RGB(0,128,0),       // PIN_CONNECTION_TYPE_VIDEO
    RGB(255,128,0),      // PIN_CONNECTION_TYPE_SUBTITLE
    RGB(128,64,128)     // PIN_CONNECTION_TYPE_MIXED
};

There is also a red-orange highlight in the filters dialog when using search box.

Colorization of filters is understandable. But what is this:

Or this

It's just a decoration. Like red in GraphStudioNext icon it is not supposed to be an alert. No worries.

The red decoration header of a property pages is to identify that this pages is implemented in graphstudionext. For some pin/filter interfaces graphstudionext has own property pages so the user can test this interface. In the original graphstudio these pages had a blue header, with the fork, this color was changed to red.

"PNP" are filters from Plug and Play devices, like a capture box or stick like in your example. The color in the filters dialog represents filter type or red if the filter dll is missing.

Ok, I got it about property pages. I didn't understand the answer about the filter insert dialog. This is red, because I have PNP filters?

Btw, what exclamation mark means :)?

Btw, what exclamation mark means :)?

Filter registration information is present, however the DLL file with the implementation is no longer available (esp. incorrect deinstallation of the COM server).

It might so happen (looking at the screenshot above) that for DMOs it reports incorrect information.

[cplussharp]

Plug&Play Filters are purple. As roman said, the red exclamation mark means that the dll-file was not found.

But there seems to be a problem finding the dll file of the DMOs, when you filter for "(ALL) DirectShow Filters". If you switch to "(ALL) DMO Filters" the dll files are found.

Thank you, it's much more clear now. Great program, btw, I love it.

So the area with comboxes I outlined in the screenshot is red because of the missing DLLs or something else? Or it's a decoration :).

Cool to know.
Would it be possible to implement a "pop-up info box" when you hover mouse arrow over the exclamation mark?
