Topic: Show hatch patterns dialog in BricsCAD

[dankobananko]

Hello.

I am using this function in autocad to show dialog with hatch patterns.

Code: [Select]

   [DllImport(
        "acad.exe",
        EntryPoint =
          "?acedHatchPalletteDialog@@YA_NPB_W_NAAPA_W@Z",
        CharSet = CharSet.Auto
      )
    ]

    static extern bool acedHatchPalletteDialog(
      string currentPattern,
      bool showcustom,
      out string newpattern
    );

Is there BricsCAD equivalent to this?

For BricsCAD, you'll need to change the module name to e.g. "brx24.dll".

Thank you on help, I tried that and getting dialog from first attachment (missing all acad pattern names).

when apply this pattern getting error from second attachment.

Just an observation, your using predefined in your code, but your showing the custom tab.
I didn’t see a “Srafura” hatch , maybe this is a translation issue?

"Srafura" iz just string variable of hatch pattern name, when user
select it from dialog.

Regarding dialog which is visible, you are right but trying to figure
out how to show identical pattern list in BricsCAD as in AutoCAD.

ok, this works in Python. if you retrieve a hatch from the custom tab, you must use kCustomDefined

bool  acedGetPredefinedPattens(AcStringArray& patterns); is missing in BRX
might be handy to have

[dankobananko]

Tomorrow I will test it, but I am sure it works well.

Thank you for your help...I appretiate it..

Still couldn't run this dialog with predefined patterns with .net, this is screenshot from BricsCAD application.

This function return just custom patterns which I don't need.

[DllImport("brx24.dll", EntryPoint = "?acedHatchPalletteDialog@@YA_NPEB_W_NAEAPEA_W@Z", CharSet = CharSet.Auto, CallingConvention = CallingConvention.Cdecl)]

[It's Alive!]

you called ?acedHatchPalletteDialog@@YA_NPEB_W_NAEAPEA_W@Z with false?

[It's Alive!]

my python wrapper is

Code - C++: [Select]

1. extern bool acedHatchPalletteDialog(const wchar_t*, bool, wchar_t*&);
2.  
3. std::string EdCore::hatchPalletteDialog(const std::string& pattern, bool showCustom)
4. {
5.     RxAutoOutStr outstr;
6.     acedHatchPalletteDialog(utf8_to_wstr(pattern).c_str(), showCustom , outstr.buf);
7.     return outstr.str();
8. }
9.  

Code - Python: [Select]

1. def PyRxCmd_doit2():
2.     try:
3.         res =  Ed.Core.hatchPalletteDialog("", False)
4.     except Exception as err:
5.         traceback.print_exception(err)
6.

That was problem, was true, after change to false everything is fine.

Thank you very much.....
