General

TokenNames common to most controls, such as x,y,w,h,text,idc... are not listed here.

Buttons are one way to add interactivity to your dialogs. Their corresponding type property is CT_BUTTON.

Buttons can have different states (see screenshot) and will render slightly different to give the user a visual feedback on the button's state:

  • Enabled: the button has not been disabled, it currently doesn't have any mouse or keyboard related focus
  • Disabled: the button has been explicitly disabled. It will not be clickable.
  • Enabled + Focused: As enabled; additionally it will have a small border of the color defined in the colorFocused property. This occurs when the button currently has focus (ie. is the default button or has been selected via the Tab key).
  • Enabled + Active: As enabled; additionally it will have a different background as specified in the colorBackgroundActive background. This occurs when the mouse is currently hovering over an unfocused button.
  • Enabled + Active + Focused: The combined result of the above two states. The mouse is currently hovering over the button in question and it has input focus.

Button can also have code attached to it in the action property. This code will be run when the button is clicked. Most often, you will have at least one button that closes the dialog via closeDialog. In this case you can provide 0 as the right-side parameter to close the currently open dialog.

Reserved IDCs

The engine reserves:

  • IDC = 1 for (contextually) OK, or CONTINUE
  • IDC = 2 for (contextually) CANCEL, ESCAPE, ABORT

If you use these idc values, no action, no script, no event handler will operate on them.


CT_BUTTON=1

Name Type Required Remark Script
type Integer Yes Control type: 1 (or CT_BUTTON, if using constants) N/A
style Integer Yes Display options:
  • 0 (ST_LEFT): Text is left-aligned.
  • 1 (ST_RIGHT) : Text is right-aligned.
  • 2 (ST_CENTER): Text is centered.
N/A
action String No Script command(s) to execute when button is pressed.
Must use double quotes; single quotes or curly brackets will not work.

The variable "this" is available, and contains the unit that pressed the button, but unlike User Interface Event Handlers no "_this" information about the current control is passed.

buttonSetAction
borderSize Float Yes If > 0 then a background (in the color defined in 'colorBorder') is drawn behind the button.

It extends to the left by the distance defined here, its height is slightly less than that of the button, and it is vertically centered. The width extends to the right, to where the drop shadow starts. Stays static when button is pressed.

N/A
colorBackground Color Yes Button's background color if not "active" (i.e. the mouse pointer is not over it). ctrlSetBackgroundColor
colorBackgroundActive Color Yes Background color if "active" (i.e. mouse pointer is over it). ctrlSetActiveColor
colorBackgroundDisabled Color Yes Background color if control is disabled N/A
colorBorder Color Yes Color of left border, defined in 'borderSize' N/A
colorDisabled Color Yes Text color if control is disabled (via ctrlEnable) N/A
colorFocused Color Yes Alternating background color.

While the control has focus (but without the mouse pointer being over it) the background will cycle between 'colorFocused' and 'colorBackground'. If both are the same, then the color will be steady.

N/A
colorShadow Color Yes Color of drop shadow behind button (not visible if button disabled) N/A
colorText Color Yes Color of text. ctrlSetTextColor
default Boolean No Whether the button will have focus upon loading the dialog. ctrlSetFocus
offsetPressedX
offsetPressedY
Float Yes The button's text & background will move by this distance when pressed.

(If a shadow is defined, it will stay in place.)

N/A
offsetX
offsetY
Float Yes Horizontal and vertical offset of drop shadow.

If 0, then shadow will be placed directly behind button

N/A
url String No URL which will be opened with default web browser. If tooltip is empty, URL will also be set as that. N/A
soundClick Sound No Sound to play when button is released after a click. N/A
soundEnter Sound No Sound to play when the mouse cursor is moved over the button. N/A
soundEscape Sound No Sound to play when the button was clicked via the mouse, and then released outside the button area. N/A
soundPush Sound No Sound to play when button is clicked. N/A
text String No Text to display. Will be vertically centered. ctrlSetText
toolTip String No Text that is shown in a little popup box when the mouse pointer is hovering over the button. ctrlSetTooltip

	x = 0; y = 0; w = 0.3; h = 0.1;

	offsetX = 0.004;
	offsetY = 0.004;

	colorShadow[] = {0,0,0,1};
	shadow = 0;
	colorBorder[] = {0,0,0,1};
	borderSize = 0.008;
	soundEnter[] = {"",0.1,1};
	soundPush[] = {"",0.1,1};
	soundClick[] = {"",0.1,1};
	soundEscape[] = {"",0.1,1};
};
class dialog
{
	class controls
	{
		class OK:rscButton
		{
			idc=1;// fixed engine constant
			x=y=w=y=whatever;
			text="OK"
			default=true;
		};
		class Cancel
		{
			idc=2; // fixed engine constant
			x=y=somewhere else
			default=false;
		};
	};
};


The following example uses almost the same code as the buttons shown in the example screenshot.

The same button four times in different states
  • Example:
class MyButton {
	idc = -1;
	type = CT_BUTTON;
	style = ST_LEFT;
	default = false;
	font = FontM;
	sizeEx = 0.03;
	colorText[] = { 0, 0, 0, 1 };
	colorFocused[] = { 1, 0, 0, 1 };		// border color for focused state
	colorDisabled[] = { 0, 0, 1, 0.7 };		// text color for disabled state
	colorBackground[] = { 1, 1, 1, 0.8 };
	colorBackgroundDisabled[] = { 1, 1, 1, 0.5 };	// background color for disabled state
	colorBackgroundActive[] = { 1, 1, 1, 1 };		// background color for active state
	offsetX = 0.003;
	offsetY = 0.003;
	offsetPressedX = 0.002;
	offsetPressedY = 0.002;
	colorShadow[] = { 0, 0, 0, 0.5 };
	colorBorder[] = { 0, 0, 0, 1 };
	borderSize = 0;
	soundEnter[] = { "", 0, 1 };	// no sound
	soundPush[] = { "buttonpushed.ogg", 0.1, 1 };
	soundClick[] = { "", 0, 1 };	// no sound
	soundEscape[] = { "", 0, 1 };	// no sound
	x = 0.4; y = 0.475;
	w = 0.2; h = 0.05;
	text = "Close";
	action = "closeDialog 0; hint ""Dialog closed. You are good to go now!""";
};

CT_ACTIVETEXT=11

The Active Text control behaves very similar to buttons. It shows up as regular text with the additional functionality that you can click and select it. The dialog's currently selected Active Text control will be underlined to indicate it's status. By default, the first Active Text control is selected. When the mouse cursor hovers over an instance of this control, it will show up in the color defined in the colorActive property.

Notice: This control doesn't render the usually common colorBackground property and colorText is replaced with color.

  • For Arrowhead, this is not true. The properties are there, and it might be an attempt to standardise, or to account for pictures

The following example uses almost the same code as the controls shown in the example screenshot.

Simple dialog with three Active Text controls
  • Example:
class MyActiveText
{
	idc = -1;
	type = CT_ACTIVETEXT;
	style = ST_LEFT;
	x = 0.75; y = 0.5;
	w = 0.2; h = 0.035;
	font = FontM;
	sizeEx = 0.024;
	color[] = { 1, 1, 1, 1 };
	colorActive[] = { 1, 0.2, 0.2, 1 };
	soundEnter[] = { "", 0, 1 };	// no sound
	soundPush[] = { "", 0, 1 };
	soundClick[] = { "", 0, 1 };
	soundEscape[] = { "", 0, 1 };
	action = "hint ""Good choice!""";
	text = "Text";
	default = true;
};
