This sample may help you to understand the usage of PaletteSet, Palette and WPF UserControl and save you some time to investigate the how and why of building these controls. I think each of of us has spent a lot of time to get these controls working.
The focus on this sample is on the interaction between AutoCAD and the UserControl, NOT on the Contents of the UserControl. That's subject for another Forum Threat.
The sample show how to encapsulate all the required actions for a PaletteSet into one class: PaletteSetMultiplePalettes
I'll show you how to add two Palettes(and UserControls) in the PaletteSet to let you better understand the relation between PaletteSet, Palette(s) and the UserControl(s).
Pay attension to the building of the PaletteSet, Palette and UserControl in the function ShowPaletteSet(..). The set Dock, Visible(3X) is crusial for having the contents scaled proparly whithin the Palettes. Also note that the UserControl size is not defined, only the minimal Sizes.
The Palettes are AutoCAD document independant, meaning that there is only one PaletteSet for the running AutoCAD session. The UserControls will be updated for each active document. This is done in the DocumentActivated event AND triggered by the Layers_CollectionChanged event.
Also shown is how the WPF button Events and WpfData is handled by the Parent Class using the ButtonClickedEventHandler. This promotes the reuse of the UserControls.
This sample is build for AutoCAD 2016. Previous versions of AutoCAD may handle the building of the PaletteSets a bit different in requirds to the Size (DeviceIndependentSize) properties.
For this sample required referenced are
- AcCoreMgd, AcDbMgd, AcMgd, AcCui, AcCustomize, adWindows.
- PresentationFramework, PresentationCore, Xaml.
- Windows Forms, WindowsFormsIntegration.
After Compile, autoload into AutoCAD using the registry or simply use NETLOAD.
The Palettes will be shown with the command: ShowPsM.
Notice the Tabs in the PaletteSet for each Palette/UserControl.
Then create or open another drawing and notice the contents of the Palette get updated.
Create Layers or Text Styles and again the Palettes will be updated.
Press one of the OK buttons and the WPF contents will be send to the ucControlX_OnOkClicked event and written to the CommandLine.
Press the Cancel button and the Palette/UserControl will be removed from the PaletteSet. When both UserControls are cancelled the PalettSet will be removed as well.
Note that this sample is A way tho handle PaletteSets/Palettes and UserControl, not THE way of doing this.
I hope that other Authors of this forum comment on this template to improve.
Good Luck.
