std::map<std::string, HUDObject> elements;

void AddObject(std::string elem_name, HUDObject obj);

void DrawPanel(int x, int y);

columns: Number of columns.

rows: Number of rows.

spacingX: Padding along x-axis.

spacingY: Padding along y-axis

width: Grid Width.

height: Grid Height.

Example: RelativeLayout

HUD_FlowPanel hudgrid2;
hudgrid2.height = 100;
hudgrid2.width = 10;
//hudgrid.columns = 5;
//hudgrid.rows = 1;

AnimatedSprite as1;
as1.LoadTexture("content\\misc\\itemNo\\ItemNo.1.png", gRenderer);
as1.BuildAnimation(0, 1, 8, 11, 0.1f);

AnimatedSprite as2;
as2.LoadTexture("content\\misc\\itemNo\\ItemNo.2.png", gRenderer);
as2.BuildAnimation(0, 1, 8, 11, 0.1f);

HUDObject hob1;
hob1.sprites = &as1;
hob1.column = 0;
hob1.row = 0;
HUDObject hob2;
hob2.sprites = &as2;
hob2.column = 1;
hob2.row = 0;

hudgrid2.AddObject("1", hob1);
hudgrid2.AddObject("2", hob2);

Example: GridLayout

Displaying a grid with two columns and one row.

//Our HUD Grid
HUD_GridPanel hudgrid;
hudgrid.height = 100;
hudgrid.width = 100;
hudgrid.columns = 2;
hudgrid.rows = 1;

//Create Sprites
AnimatedSprite as1;
as1.LoadTexture("content\\misc\\itemNo\\ItemNo.1.png", gRenderer);
as1.BuildAnimation(0, 1, 8, 11, 0.1f);

AnimatedSprite as2;
as2.LoadTexture("content\\misc\\itemNo\\ItemNo.2.png", gRenderer);
as2.BuildAnimation(0, 1, 8, 11, 0.1f);

//Bind Objects | Set row/column
HUDObject hob1;
hob1.sprites = &as1;
hob1.column = 0;
hob1.row = 0;
HUDObject hob2;
hob2.sprites = &as2;
hob2.column = 1;
hob2.row = 0;

The example above would result in the following:

See the "1" & "2" sprites? :)

Make sure to call .DrawPanel() in your main loop!
