Controls
ModernUI controls are grouped by the job they do.
Use this section when you know what kind of interface element you need and want to find the right control or factory helper.
For normal EA panels, create controls normally, assign .Id(...) to interactive controls, and handle app-level behaviour with the Event Bus.
If you already know the class or helper name, use the Controls reference.

Creating controls
Most controls can be created through Mui::... factory helpers.
MuiButtonAction *save=Mui::Button(parent,"Save");
save.Id(PANEL_ACTION_SAVE);
MuiLabel *title=Mui::Label(parent,"Status");
MuiSpinEditHost *risk=Mui::SpinEdit(parent,0.1,10.0,1.0,0.1,1,NULL,220.0,0.0);
risk.Id(PANEL_ACTION_RISK_CHANGED);You can also instantiate lower-level controls directly when you need more control.
Factory helper pattern
ModernUI factory helpers usually follow this pattern:
parent first
then important content/value arguments
then optional advanced handler where applicable
then width/heightA width or height of 0.0 usually means use the control/theme default.
Common setter style
button.Id(PANEL_ACTION_SAVE);
button.Text("Save");
button.Pad(14.0,8.0);
button.Radius(10.0);
slider.Id(PANEL_ACTION_SLIDER_CHANGED);
slider.Value(0.35);
slider.AccentColor(0xFF3B82F6);Choosing wrappers vs controls
Use fast wrappers when you want common panel structures.
Use controls directly when a wrapper hides something you need, the layout is specialised, data comes from a custom source, or you are building a reusable component.
