Draw center position (0, 0) with hairlines.

• Remove offset textboxes.
• Add "Move to center screen" button

Rewrite pan and zoom functionality. Transformations need to be independent of the drawing operations and tree-calculations.

Need to work well:

• Two buffered (drawing on two canvas) rendering.
• Pan by left button down + moving mouse.
• Zoom by mouse wheel (the center point is the current position of the mouse).
• Zoom by exact percent.
• Reset transformations.

Render selector control.

Measure calculation time to an exact endpoint (ForceMax < ?).

This change enables to use individual forces per node type or per node.

For example:
App: yellow,
ContentType: Red
Other systems: blue
Workspace: ??

Load from asm or use kavics/API.

Clicked node is selected. Previously selected node is changed to not selected. Selected node properties appear in a "Properties" popup window. Selection is cleared if the properties window is closed.

BigTreeCalc/Class1.cs

Better start positions. Starting state of the tree is too chaotic. Choose a better solution. For example: place the nodes into concentric circles. Circle radius depends on the level of the node.

Use inertia control (slowing movement to speed 0 after dragging is stopped).

Rotate all nodes around the point (0,0) by the input degree that comes from a textbox.

Zoom center needs to be the actual mouse position.

Textbox and discrete function buttons.

Settings window (for example change renderer)

Move the visible area left-right and up-down

Create library that can draw any tree to outer canvas.

(MainWindow.xaml.cs CreateTree method)

Repulsion effect can be limited by fast-calculated distance (max X or max Y).

Getting trees from various sources

• Script
  • SQL script.
  • JSON hierarchy.
  • XML file.
  • YAML file.
• Object hierarchy
  • Parent-children relation by interface
  • Type hierarchy

Persist the calculation state. The calculation/rendering can be continuable after reloading.

(MainWindow.xaml.cs CreateTree method)

• ZOOM: Function buttons: Fit to window

• ZOOM: Function buttons: Reset to 100%,

• ZOOM: Slider.

• ZOOM: Use zoom in hairlines

• ZOOM: Mouse wheel.

• ZOOM. TextBox with exact percent value..

• ZOOM: Use zoom in mouse interaction (hover).

• ZOOM: + / - buttons.

• ZOOM. TextBox with exact percent value..

• SELECTION. Every node need to be clicked. Clicked node is selected. Previously selected node is changed to not selected. Selected node properties appear in a "Properties" popup window. Selection is cleared if the properties window is closed.
