Palette set fixed size - disable resize possibility

5thSth — Sun, 29 Nov 2015 03:17:00 GMT

I've managed to get the palette set window to be fixed using this somewhat crude and brute force method:

            Timer tDelayedResize = new Timer();
            tDelayedResize.Interval = 5;
            tDelayedResize.Tick += (s, e) =>
            {
                tDelayedResize.Stop();
                //Do your ResizeEnd logic here
                //...
                _ps1.Size = constSize;
            };

            _ps1.SizeChanged += (s, e) =>
            {
                tDelayedResize.Stop();
                tDelayedResize.Start();
            };


        }

however, I'm keen on finding a more slick way of achieving fixed palette size

After some soul searching, I came to realize I can hook to windows messages (MINMAXinfo, and similar)

for test purposes, I tried doing it on a winform... but still dont have the hang of it.

my ultimate goal would be that "resize cursor" doesnt even appear when hovering over PS corner... but even a constant size would be a treat at this point (my OCD just wont give me rest on this 1 :D)

        private void button1_Click(object sender, EventArgs e)
        {
            if (hHook == 0)
            {
                // Create an instance of HookProc.
                HookProcedure = new HookProc(Form1.WinHookProc);

                hHook = SetWindowsHookEx(   //WH_CALLWNDPROCRET,
                                            WH_CALLWNDPROC,
                                            HookProcedure,
                                            (IntPtr)0,
                                            AppDomain.GetCurrentThreadId());
            }
        }

        public static int WinHookProc(int nCode, IntPtr wParam, IntPtr lParam)
        {
            //Marshall the data from the callback.
            //CWPretStruct MyHookStruct = (CWPretStruct)Marshal.PtrToStructure(lParam, typeof(CWPretStruct));
            CWPSTRUCT MyHookStruct = (CWPSTRUCT)Marshal.PtrToStructure(lParam, typeof(CWPSTRUCT));

            if (nCode < 0)
            {
                return CallNextHookEx(hHook, nCode, wParam, lParam);
            }
            else
            {
                MINMAXINFO mmi = (MINMAXINFO)Marshal.PtrToStructure(MyHookStruct.lparam, typeof(MINMAXINFO));
                
                mmi.ptMaxSize.x = 300;
                mmi.ptMaxSize.y = 300;
                System.Runtime.InteropServices.Marshal.StructureToPtr(mmi, MyHookStruct.lparam, true);

                return CallNextHookEx(hHook, nCode, wParam, lParam);
            }
        }

any tips on how to override such features would be graetly appreciated;
If any1 can offer a better solution than my PS code, or a tip when it comes to Hooks, I'd be more than grateful!

Sorry, playing with Fixed values for sizes in de WPF definitions did not prevent the Panel to be resized. It prevent the UserControl to be resized but i think that's not enough

can you pls post the code for WPF definition override(if you've done it through hooks). maybe I learn something from it.

I doub't having code that benefits you because youre code already exceeded mine.

I "fixed" the sizes in the XAML to see what the behaviour would be for the Palette(set)-- so no hooks.

The result is that the UserControl stays fixed but the Palette keeps resizing, and it does not prevent the resize pointer to popup.

thanks for your reply. I'll try getting some more help on c#,c++ forum if no1 else chips in.

As for PS, its a shame that it doesnt have an "on event ended" event. I've tried a bunch of techniques, (derived classes, and INotifyPropertyChanged, but proved I wasnt skilled enough :()
