Docked Dialog Problem with width of CUSTOMGUI_FILENAME

datamilch

hi there,
i'm working on a command plugin with gedialog, that i want to dock in the layout.
one of the gui elements is AddCustomGui c4d.CUSTOMGUI_FILENAME.
the paths that are stored can be quite long.
the problem is, that the dialog wants to show the complete string, which makes the dialog extremely wide.
this only happens when the dialog is docked. then i can not scale the dialog smaller then the length of the string/filename.
if the dialog is not docked i can scale it smaller and the overflowing string is hidden.
sadly AddCustomGui has no properties initw and inith. i tried some combinations of flags but had no success.
am i missing something?

i could place the element in a scrollgroup, but then the "open document" button might be hidden in the part that is scrolled away.
any other options or workarouds?

cheers, sebastian

here is the code

Hi @datamilch,

Although I highly suspect this to be a bug, I'll need more time to double check it. I'll update you further, once have a more clear vision on this.

Cheers,
Ilia

Thanks for the preliminary feedback.
I'll wait patiently

Hi Sebastian,

Thanks for your patience. TLDR; it's a bug but you still need to set minimal width.

The issue is twofold:

For this UI element to work as intended you need to specify the minimal width argument minw, for example using the c4d.gui.SizeChr() function:
self.AddCustomGui(self.ID_TEXT_1, c4d.CUSTOMGUI_FILENAME, '', c4d.BFH_SCALEFIT, c4d.gui.SizeChr(80), 0, bc)
There's currently a bug, which prevents this from working properly. The fix is going to be included in one of further Cinema 4D releases.

After the fix is released, given you're using the minw argument, the issue wouldn't be there anymore. Thanks for drawing our attention to this issue!

Cheers,
Ilia

hi, thanks for the info.
i just updated to 2025.2.0 ... but i suppose the fix is not in this one yet? not sure when the release date was ...

Hi Sebastian,

correct, it hasn't been included into 2025.2.0. The next minor release will likely have it fixed though.

Cheers,
Ilia
