Dynamic Properties true color combobox

[BerndCuder8196]

Hi,

does anybody know how to implement an color selection in OPM for true color?

Normally i implement it like this:

//IDynamicProperty
STDMETHODIMP Chtextcolor::GetCurrentValueName( /*[out]*/BSTR* pBstrName)
{
    *pBstrName = ::SysAllocString(L"ACAD_COLOR");

    return S_OK;
}

But this will only shows the color combobox for AutoCAD ACI, not for true color.

THanks, Bernd

What wrong?

Hello Alexander,

thanks for your reply.

For the entitys color property this is ok, but my custom entity have 2 AcCmColor i have implement in OPM via IDynamicProperty.

I use IDynamicProperty::GetCurrentValueName with ACAD_COLOR to show the standard AutoCAD color combo box.

But this shows only the combobox for Index Color (like CAcUiColorComboBox for dialogs), not with the tabs for True Color and Color Books (like CAcUiTrueColorComboBox for dialogs).

Why you implement this property via IDynamicProperty?

It is easy implement as static property:

STDMETHOD(get_MyColor)(/*[out, retval]*/ ACAD_COLOR* pVal);
STDMETHOD(put_MyColor)(/*[in]*/ ACAD_COLOR newVal);

Thanks for your reply.

Unfortunally i need insert add. propertys in OPM also for AutoCAD Objects, but i think this will not work witch static property or can i register this for example an AcDbDimension?

By the way, i want test static property for my custom entitys, but when i create with objectarx wizard and Use ObjectARX ATL Extensions for custom entitys then there are 2 files missing and not created (MyProject.h and MayProject_i.c). What im doing wrong?

And is there no way to implement truecolor combobox in OPM via dynamic properties, olny ACI combo?

thanks Bernd

OK, i was able to create a COM Wrapper and implement it for my custom entity.

For true color combobox you need to implement as

STDMETHODIMP get_koteColor(IAcadAcCmColor **pVal);
STDMETHODIMP put_koteColor(IAcadAcCmColor *newVal);

and not

STDMETHOD(get_MyColor)(/*[out, retval]*/ ACAD_COLOR* pVal);

STDMETHOD(put_MyColor)(/*[in]*/ ACAD_COLOR newVal);

thanks, Bernd

IMHO with dynamic property you can not get combobox with true color but can use button with dialog in which you can use acedSetColorDialogTrueColor for selecting truecolor.

[BerndCuder8196]

Hi Alexander,

This was my first idea, an text box with the color name (ByLayer, 135, or RGB value) and an button for the true color dialog.
I think it is also possible to add an custom combo (derived from AutoCAD color combo) but my knowledge for this are to poor.

Sorry but it is impossible to derive from AutoCAD color combo. Also I can not found any possibility to create own-drawn button as dynamic property.

[BerndCuder8196]

Ok, I have found a funny thing in AutoCAD.

AutoCAD itself didn't show the true color combo for nested colors in OPM.

You can create an dimension style with true color for text and lines and then create an dimension with this true colors.

But in OPM these colors broken down to ACI and you can only change to another ACI color, not to an true color. Maybe they have forgotten to implement it. 🙂

@Anonymous, in Dynamic Property i was able to show the color name in OPM as text and add an ellipse button that calls the AutoCAD true color dialog. Only the color itself is not visible, but this is more than users can do with e.g. dimension text color 🙂

Yes. I was referring to this method and the impossibility of show a color icon picture in dynamic property.

i remember using something like this in the wrapper, for a complex object in my c++/arx days many moons ago:

in the .h

	STDMETHOD(get_ColorHatch)(/*[out, retval]*/ VARIANT *pv);
	STDMETHOD(put_ColorHatch)(/*[in]*/ VARIANT var);

in the .cpp

STDMETHODIMP CClosedPolygonWrapper::put_ColorHatch(VARIANT var)

	static AcGsColor AcadColors [] =

hope that will help somehow...

It will be helpful but not for dynamic property. 🙂

I tried this yet it did not work.for my custom color property.

[KIMHENGHOR98]

Would you share me a custom color property?

[BerndCuder8196]

Here is an example for an custom entity (CCNCTextLine).

The color related functions are:

STDMETHODIMP get_textColor(IAcadAcCmColor **pVal);
STDMETHODIMP put_textColor(IAcadAcCmColor *newVal);

Kind regards, Bernd

I need dynamic property custom color😳
