Show

Availability

Available since 1.1.0 version.

Overview

Makes a hidden PrismaView visible. This method sets the view’s visibility flag to allow it to be rendered in the next frame, enabling you to show previously hidden UI elements without recreating them.

Efficient UI Management

Use Show and Hide to toggle UI visibility instead of destroying and recreating views. This approach is more efficient and preserves the view’s state.

Syntax

void Show(PrismaView view);

Parameters

view (required)

• Type: PrismaView
• Description: The PrismaView to make visible

Return Value

This method returns void.

Usage Examples

Basic Usage

// Show a previously hidden view
PrismaUI->Show(view);

Behavior Details

Operation Queue

If the view is already visible, the operation is ignored with a debug log message.

• Sets the isHidden flag to false
• View begins rendering in the next frame
• If view is already visible, operation is silently ignored
• Does not affect focus state - use Focus separately if needed

Best Practices

State Management

Combine Show with Focus when you want to both display and activate a view for user interaction. Use Show alone when you want to display a view without capturing input.

• Pair with Hide: Use Show and Hide as complementary operations
• Check State: Use IsHidden to check visibility before showing
• Focus Management: Call Focus separately if input interaction is needed
• Performance: Prefer show/hide over destroy/create for temporary UI

Common Issues

Troubleshooting

If a view doesn’t appear after calling Show:

• Verify the view is valid using IsValid
• Check that the view’s z-order isn’t behind other views
• Ensure the view’s HTML content is properly loaded
• Verify no other views are blocking it
• Check that the view was previously hidden, not destroyed
