Just a little follow-up on this: It would be very much appreciated if there was like a Message() coming in, or a callback, or some other way to simply present any BaseLink members of the NodeData to an AliasTrans. Cheers, Frank

Thank you! :-)

Nice, Manuel, thank you! I guess, I'll try the SetDParameter() approach, too, in good time. Cheers, Frank

I’m confident they will find out ;-) Thanks for everything!

OK, thanks!

OK, I got it. Once it's all figured out, the solution seems laughably simple. In case anybody else needs to maintain R20 compatibility and wants to use custom icon overlays, here's a solution: In MyObject class declaration: (R20 code) class MyObject : public ObjectData { INSTANCEOF(MyObject, ObjectData); // ... private: #if API_VERSION < 21000 BaseBitmap *_customIcon; ///< Used to store a node's custom icon in R20 #endif }; public: #if API_VERSION < 21000 MyObject() : _customIcon(nullptr) { } ~ MyObject() { if (_customIcon) BaseBitmap::Free(_customIcon); } #endif In MyObject::Message(): (R20 code) const BaseContainer &dataRef = op->GetDataInstanceRef(); // // 1. Copy default icon into customIcon // // Load default icon IconData defaultIconData; if (!GetIcon(node->GetType(), &defaultIconData)) return false; // Free _customIcon if it has been allocated before, because // it will now receive the pointer to a newly allocated BaseBitmap. if (_customIcon) BaseBitmap::Free(_customIcon); // Get the actual bitmap that is our icon _customIcon = defaultIconData.GetClonePart(); if (!_customIcon) return false; // // 2. Blit overlay into customIcon // // Load overlay icon IconData overlayIcon; const Int32 overlayIconId = MyFunctionToGetTheIconId(); if (overlayIconId == NOTOK) return false; const Bool overlayIconloaded = GetIcon(overlayIconId, &overlayIcon); if (overlayIconloaded) { BlitOverlayBitmap(overlayIcon.bmp, _customIcon, overlayIcon.x, overlayIcon.y, overlayIcon.w, overlayIcon.h, 32, 32); // // 3. Set cid->dat to use customIcon // cid->dat->bmp = _customIcon; cid->dat->x = 0; cid->dat->y = 0; cid->dat->w = _customIcon->GetBw(); cid->dat->h = _customIcon->GetBh(); cid->filled = true; } And BlitOverlayBitmap(), a variation of your BlitOverlayIcon(): void BlitOverlayBitmap(BaseBitmap *overlay, BaseBitmap *dest, Int32 x, Int32 y, Int32 bw, Int32 bh, Int32 xOffset, Int32 yOffset) { if (!overlay || !dest) return; BaseBitmap *overlayAlpha = overlay->GetInternalChannel(); BaseBitmap *destAlpha = dest->GetInternalChannel(); const Int32 destW = dest->GetBw(); const Int32 destH = dest->GetBh(); if (bw > destW) bw = destW; if (bh + yOffset > destH) bh = destH - yOffset; if (bw + xOffset > destW) bw = destW - xOffset; UInt16 aa, a, rr, r, gg, g, bb, b; aa = a = rr = r = gg = g = bb = b = 0xff; for (Int32 py = 0; py < bh; py++) { for (Int32 px = 0; px < bw; px++) { // get color and alpha from overlay icon overlay->GetPixel(x + px, y + py, &r, &g, &b); overlay->GetAlphaPixel(overlayAlpha, x + px, y + py, &a); // get color and alpha from background icon if available dest->GetPixel(px + xOffset, py + yOffset, &rr, &gg, &bb); if (destAlpha) { dest->GetAlphaPixel(destAlpha, px + xOffset, py + yOffset, &aa); } // blend overlay color against existing icon background color Float blend = a / 255.0; dest->SetPixel(px + xOffset, py + yOffset, (Int32)Blend(rr, r, blend), (Int32)Blend(gg, g, blend), (Int32)Blend(bb, b, blend)); // use only the overlay alpha if the opacity is higher to keep the original icon complete // and only in case the background has an alpha at all if (destAlpha && aa < a) { dest->SetAlphaPixel(destAlpha, px + xOffset, py + yOffset, a); } } } } Thanks for patience & support! Cheers, Frank

Hi Frank, sorry for coming late to the party, the API changed within the R21 where by default the icon is not more filled because it's up to you to fill it with what you need. Just in case for other people, not interested in C++ (since the manual is pretty obvious) there is a Python example in Where you can have custom icons, you can find an example of how to achieve custom icon within Python in py-custom_icon_r21.pyp. Cheers, Maxime.

Hmmmm, well, on the one hand this function is a nice thing: It really does do the escaping for me, so the spaces in the URL are correctly replaced with "%20". But it does not handle anchors in a URL. This URL works fine: file:///Applications/Maxon/Cinema 4D R22/plugins/myplugin/help/content/omyobject/omyobject.html But this URL is not opened, instead an error (code -43) is thrown: file:///Applications/Maxon/Cinema 4D R22/plugins/myplugin/help/content/omyobject/omyobject.html#MYOBJECT_ATTRIBUTE That is a pity.

It works like a charm! Thank you again! I was surprised at how little code was required. Sharing is caring. In case anyone needs it, here's the code: #include "ge_prepass.h" #include "c4d_general.h" #include "c4d_baselinkarray.h" #include "c4d_basedocument.h" /// /// \brief Registers observers and sends messages to them. /// class Observable { public: /// /// \brief Subscribes a new observer. /// /// \param[in] observer Pointer to an AtomGoal /// \param[in] doc The document that owns the AtomGoal /// /// \return A maxon error object if anything went wrong, otherwise maxon::OK /// maxon::Result<void> Subscribe(C4DAtomGoal *observer, BaseDocument *doc); /// /// \brief Unsubscribes an observer /// /// \param[in] observer Pointer to an AtomGoal that has previously been subscribed /// \param[in] doc The document that owns the AtomGoal /// void Unsubscribe(C4DAtomGoal *observer, BaseDocument *doc); /// /// \brief Sends a messages to all subscribed observers /// /// \param[in] type Message type /// \param[in] doc The document that owns the subscribed observers /// \param[in] data Optional message data /// void Message(Int32 type, BaseDocument *doc, void *data = nullptr) const; private: BaseLinkArray _observers; }; maxon::Result<void> Observable::Subscribe(C4DAtomGoal *observer, BaseDocument *doc) { if (!observer) return maxon::NullptrError(MAXON_SOURCE_LOCATION, "Observer must not be nullptr!"_s); // Check if this observer is already registered const Int32 observerIndex = _observers.Find(observer, doc); if (observerIndex != NOTOK) return maxon::OK; // Register new observer if (!_observers.Append(observer)) { return maxon::OutOfMemoryError(MAXON_SOURCE_LOCATION, "Failed to add observer to the list!"_s); } return maxon::OK; } void Observable::Unsubscribe(C4DAtomGoal *observer, BaseDocument *doc) { if (observer && doc) { const Int32 observerIndex = _observers.Find(observer, doc); if (observerIndex != NOTOK) { _observers.Remove(observerIndex); } } } void Observable::Message(Int32 type, BaseDocument *doc, void *data) const { for (Int32 i = 0; i < _observers.GetCount(); ++i) { C4DAtomGoal *atom = _observers.GetIndex(i, doc); if (atom) { atom->Message(type, data); } } }

Oh wait, I think I found a way. In case anybody else wants to know, here it is... In the PrefsDialogObject: Bool MyPrefsDialog::SetDParameter(GeListNode *node, const DescID &id,const GeData &t_data,DESCFLAGS_SET &flags) { BaseContainer* bc = MyPlugin::GetPreferences(); if (!bc) SUPER::SetDParameter(node, id, t_data, flags); switch (id[0].id) { // If PREFS_MYPLUGIN_SOMEVALUE was changed, store value and notify plugin objects in all open documents. case PREFS_MYPLUGIN_SOMEVALUE: bc->SetInt32(PREFS_MYPLUGIN_SOMEVALUE, t_data.GetInt32()); flags |= DESCFLAGS_SET::PARAM_SET; // Iterate open documents for (BaseDocument *doc = GetFirstDocument(); doc; doc = doc->GetNext()) { // Send broadcast message to each document, use unique ID doc->MultiMessage(MULTIMSG_ROUTE::BROADCAST, MyPlugin::UNIQUE_ID_PREFS, nullptr); } GeUpdateUI(); return true; } return SUPER::SetDParameter(node, id, t_data, flags); } And then, in the plugin object: Bool MyPluginObject::Message(GeListNode *node, Int32 type, void *data) { if (type == MyPlugin::UNIQUE_ID_PREFS) { GePrint("Aha! My prefs have changed!"_s); return true; } return SUPER::Message(node, type, data); }

I guess VirtualBox is just not a good choice then. Damn. But thanks for the answer! Cheers, Frank

Hm, not bad. In deed, it has the potential to look more like the "normal" HUD, without doing hacky stunts. And it is a bit faster than DrawMultipleHUDText(). However, even if I only draw 4 texts using this code, the framerate on my iMac is down to 24 fps (tested in R21). Using my own code, I get 127 fps. I'll see if it can be optimised more (e.g. by making the clip map a member of MyClass so it does not have to be allocated for every draw call. Cheers, Frank EDIT: And it gets slower in a linear way. drawing 4 texts only gives me 12 fps. So, it looked promising, and I thank you very much for the code, as it gives me some new inspiration on how to do text drawing in the viewport), but for what I need to do (drawing > 30 texts on average), it is not suitable.

Always using the threadIndex, of course :-) Thanks, I'll try that!

Hi @fwilleke80, unfortunately, I confirm the shader effect is almost always dirty. I don't have any real workaround maybe you can retrieve all noises and compute their dirtiness, but this is indeed a very hard topic to handle all cases because you will also need to handle the actual parameter of the shader effector itself. Cheers, Maxime.

Ah, great, thank for checking! Then I don't need to worry about my bmp code :-) Cheers, Frank

arff, that's really strange, I'll send you a simple example and see if the error still happen on your system.

Almost perfect, thanks. It kinda only works half ok, I noticed. The thing is, all shaders are always sampled in UV space. I tried adding the 3D position data for sampling, too, by setting volumeData.p to the global position of the point to sample, in SetSamplingContext(). but it is being ignored. For example, if the Shader is a Noise shader, I can set it to whatever space I want, the result is always the same. With my old code, that worked. It just couldn't sample certain shaders (Layer Shader, Earth Shader, etc). Now, those shaders work, but sampling seems restricted to UV space. How can I sample those shaders in Texture Space, Object Space, and World Space (Camera, Screen, and the others can be neglected)? Thanks in advance, Frank

Hi Frank sorry for the delay needed for this issue, I get the time to look at it, and this is the thing I should have checked first, but either in a GeDialog with a Layout created in a script, I'm not able to hide a tab. Since you said it was working previously, could you confirm you don't want to hide only the content (in your case the 3 StaticText) but also the tab in the tab entry, isn't? If yes could you provide a code sample because I would say even in a normal case I'm not able to reproduce. import c4d class Dlg(c4d.gui.GeDialog): def CreateLayout(self): if self.TabGroupBegin(10001, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, tabtype=c4d.TAB_TABS): if self.GroupBegin(10010, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, title="First Tab"): self.AddStaticText(10011, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, name="Text01") self.GroupEnd() if self.GroupBegin(10020, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, title="Second Tab"): self.AddStaticText(10021, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, name="Text02") self.GroupEnd() self.GroupEnd() self.AddButton(10030, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, name="Remove First Tab") return True def Command(self, id, msg): if id == 10030: print self.HideElement(10010, True) print self.LayoutChanged(10001) return True def main(): global dlg dlg = Dlg() dlg.Open(c4d.DLG_TYPE_ASYNC) # Execute main() if __name__=='__main__': main() To me, the only way to remove a tab is to flush the complete group master of the TabGroup and re-add tabs except for the one you don't want. Cheers, Maxime.

Hello to all @zipit said in GetFontDescription() on Windows and Mac: FONT_FLAGS Thank you i miss flags in https://plugincafe.maxon.net/post/58961

hi, I think you have access to the beta and BL so you can create a suggestion :) Cheers, Manuel
