GUILayout Positioning for SelectionGrids and Buttons

Archived Forums Questions & Answers

Still figuring out the layout of GUI objects. The task is to make a SelectionGrid (which may have an arbitrary number of rows), and then beneath that, a column of buttons individually aligned. They’re placed in a GUI area comprising the bottom 100 pixels of the screen, and I try to separate them with horizontal and vertical delimiters. However no matter how I try to lay it out, the buttons get overlaid on top of the selection grid, as if BeginHorizontal doesn’t recognize the positioning of the SelectionGrid, whose rect I placed at the top of the GUI area:

Selection Grid and buttons getting overlayed in the same space.

Code below. I left some of the horizontal/vertical delimiters that I’ve tried (to no avail) commented out:


GUILayout.BeginArea(Rect(0,Screen.height-100,Screen.width,100));
GUILayout.BeginVertical();
//GUILayout.BeginHorizontal();
toolbarSelected=GUI.SelectionGrid(Rect(0,0,Screen.width,50),toolbarSelected,toolbarStrings,5);
//GUILayout.EndHorizontal();
for(var bText in buttonTexts){
	//GUILayout.BeginHorizontal();
	if(GUILayout.Button(bText)){
		//bla				
	}
	GUILayout.FlexibleSpace();
	//GUILayout.EndHorizontal();
}
GUILayout.EndVertical();
//GUILayout.FlexibleSpace();
//GUILayout.EndHorizontal();
GUILayout.EndArea();

Are GUI.SelectionGrids and GUI.Toolboxes not considered elements for the layout arrangement of GUILayout.BeginHorizontal and BeginVertical?

GUI.SelectionGrid and GUI.Toolbar are ignored by the layout arrangement, because they’re positioned in fixed layout mode.
To use automatic layout, you need to use GUILayout.SelectionGrid like this:

toolbarSelected = GUILayout.SelectionGrid(toolbarSelected, toolbarStrings, 5, GUILayout.Height(50));
