Function Documentation

accentButton()

bool menu_theme::accentButton	(	const char *	label,
		const ImVec2 &	size )

Bright accent call-to-action button.

Here is the caller graph for this function:

applyStyle()

void menu_theme::applyStyle

(

)

Apply the cohesive white terminal style (colors + rounding + spacing).

Note

Call once after ImGui::CreateContext() (and after ImGui::StyleColorsDark()).

Here is the caller graph for this function:

beginPanel()

bool menu_theme::beginPanel	(	const char *	idAndTitle,
		float	baseWidth,
		float	baseHeight,
		bool	showTitle,
		ImGuiWindowFlags	extraFlags = 0 )

Begin a centered, responsive, chromeless panel.

Parameters

idAndTitle	Window id; also drawn as the panel title when showTitle is true.
baseWidth	Design width at 1280x720 (scaled up/down with the display).
baseHeight	Design height at 1280x720.
showTitle	When true, draws a large accent title + underline rule.
extraFlags	Additional ImGuiWindowFlags to OR in.

Returns

ImGui::Begin() result. Always pair with endPanel(), even when this returns false.

Here is the call graph for this function:

Here is the caller graph for this function:

beginScrollBody()

bool menu_theme::beginScrollBody	(	const char *	id,
		float	footerHeight )

Begin a scrollable body region inside a panel that reserves footerHeight pixels at the bottom for sticky action buttons.

Pair with endScrollBody(); content rendered between the calls scrolls vertically while callers can render footer widgets after endScrollBody().

Parameters

id	Unique child id.
footerHeight	Height in pixels to reserve below the scroll body (button rows + spacing).

Returns

True when the child is visible (always pair with endScrollBody regardless).

(

SDL_GPUDevice *

device

)
