Re: How to update bullets in tdbRichViewEdit?

TRichView has a limitation: all list markers in the list (more exactly, in the list level) must have the same font. So, if you want to apply font only to the selected markers, it can be implemented only by creating a new list with the proper font, and applying it instead of the existing list. It's o...

Re: How to update bullets in tdbRichViewEdit?

If bullets of the same list appear outside the selected fragments, do you want to change their size as well?

Re: PrintPreview with images and text

Sorry, I see nothing wrong with your "bad" file.
All indents are zeros,
This is how it looks after loading in "Editor 2" demo:

LeftMarign = 5 pixels, I added a green line showing it.

Re: RVMedia doesn't work with 2 or more same webcam

Currently, I have no ideas about optimization of RVMedia. You can try using RenderMode = rvmrmOpenGL in viewers, but I do not think it will help a lot in this case. Probably, in future, we will implement using OpenGL/DirectX for displaying multiple videos in a single window, it may help. But it is n...

Re: Register in file Video on Server

Unfortunately, the current version of RVMedia allows recording MJpeg videos only from TRVCamera component. The next update will improve the situation. TRVMediaServer components itself does not decode video, so it alone cannot be used to record it. However, you can create a client (TRVCamSender + TRV...

Re: RVMedia doesn't work with 2 or more same webcam

I mean it may be not a software, but a hardware problem, if all these cameras at the end are connected to a single USB port, it does not have enough bandwidth to work with them. The developer said that you main need not a hub connected to existing USB port but a card adding new USB ports, like this ...

Re: RVMedia doesn't work with 2 or more same webcam

Do these cameras work at the same time in another application?

Do you use a USB hub connected to the same USB port? The programmer said that one USB port with connected USB hub does not have enough power for multiple web cameras. And you need USB host controller card.

Re: Ctrl+A

If you use RichViewActions, there is TrvActionSelectAll, it has Ctrl+A shortcut by default. If you do not use RichViewActions, you can use the standard action TEditSelectAll. Or you can create a menu item or a toolbar button, assign its ShortCut = Ctrl+A, and call in OnClick: rve.SelectAll; rve.Inva...

Re: Custom Item Type, OnItemAction

1. When user press Enter, a new item must be added using the current text style. rvprDoNotAutoSwitch should prevent switching to this style, so, if the text item is protected, new items must not be created using this style when the user pressed Enter at the end of the paragraph. If it still happens,...

Re: PrintPreview with images and text

I still think that the problem is in indents. When you apply a paragraph list (bullets/numbering) to the paragraph, you also apply the list level margin. It overrides paragraph's LeftMargin (or RightMargin, for right-to-left paragraphs). You can save this document as RVF file and send to me, or atta...

Re: Problem with MergeCells and SaveRTF

I included your unit in a new project compiled with the newest version of TRichView (16.13.5), and the table loaded from RTF is exactly the same as it was originally created.
Try to install a new TRichView version and re-test.

Re: Camera Recomendation

First we need to find why it is not displayed.
Even if RVMedia cannot recognize a camera at the specified address, it can display any video stream in MJpeg or H.264 format (with the help of FFmpeg or GStreamer).

Currently, I cannot view your video stream even in VLC.
