<short>The base class for TColorBox.</short>

<descr>
|
|
<p>
|
|
<var>TCustomColorBox</var> is a <var>TCustomComboBox</var> descendant which implements the base class for <var>TColorBox</var>. TCustomColorBox displays available colors in a combo-box control. Each item in the control has a small rectangle where the color is displayed (swatch) and the color name.
|
|
</p>
|
|
<p>
|
|
The <var>Style</var> property is used to configure the list of available colors and their display names. Style may also trigger use of the <var>OnGetColors</var> event handler to get the items displayed in the combo-box control.
|
|
</p>
|
|
<p>
|
|
The <var>ColorRectWidth</var> and <var>ColorRectOffset</var> properties can be used to control the size and spacing for the color swatch displayed for the list items.
|
|
</p>
|
|
<p>
|
|
<var>Colors</var> allows indexed access to the <var>TColor</var> values in the list of items. When included in the Style property, colors like <var>clDefault</var> and/or <var>clNone</var> may be included in the list of Colors. The <var>DefaultColorColor</var> and <var>NoneColorColor</var> properties can be used to specify the TColor values used for those color constants.
|
|
</p>
|
|
<p>
|
|
ColorNames allows indexed access to the names for the values in Colors.
|
|
</p>
|
|
<p>
|
|
Do not create instances of TCustomColorBox; use the TColorBox descendant instead.
|
|
</p>
|
|
<p>
|
|
Use <var>TCustomColorListBox</var> / <var>TColorListBox</var> to display color names and values in a list box control.

PickCustomColor is a Boolean function used to select a custom color rather than one of the standard colors in the Colors property.
|
|
</p>
|
|
<p>
|
|
PickCustomColor is used when cbCustomColor is included in the Style for the control and ItemIndex is set to 0. This position was reserved for a custom color when the list of colors was loaded for the Style settings in the control.
|
|
</p>
|
|
<p>
|
|
PickCustomColor uses an existing value in ColorDialog when assigned, or creates the ColorDialog when needed. It executes the ColorDialog to get the color selection for the control. The custom color selection is stored as the first TColor value in the Items for the control. When a color is successfully selected using the dialog, the return value is set to <b>True</b> and the control is redrawn.
|
|
</p>
|
|
<p>
|

The color selection dialog is not displayed at design-time, and the return value is always set to <b>False</b>.

<p>
|
|
ColorRectWidth is an Integer property which contains the number of pixels used to draw the color sample (or swatch) for each of the Colors in the combo-box control. The height is determined using the item height for the combo-box control.
|
|
</p>
|
|
<p>

If an explicit value has not been assigned to the property, the value in cDefaultColorRectWidth is scaled to the current display density and used in the property value.

Setting a new value for the property causes the control to be redrawn.

Style is a TColorBoxStyle property with settings to determine the colors available in the control and their display style. Include values from the TColorBoxStyles enumeration to enable a particular setting. For instance:
|
|
</p>
|
|
<dl>

4 extended colors (as defined in graphics.pp); like clMoneyGreen, clSkyBlue, et. al.
|

</dd>
|
|
<dt>cbSystemColors</dt>
|
|
<dd>System colors (as defined in graphics.pp); like clScrollBar, clWindow, clForm, .et. al.</dd>
|
|
<dt>cbIncludeNone</dt>
|
|
<dd>Includes clNone in the list of colors.</dd>

<dt>cbPrettyNames</dt>

Uses "pretty" names in the color names instead of the color value; like Red for clRed.
|
|
</dd>
|

<dt>cbCustomColors</dt>
|
|
<dd>Uses the OnGetColors event handler to get the list of colors.</dd>
|
|
</dl>
|
|
<p>
|
|
The default value for the property is: [cbStandardColors, cbExtendedColors, cbSystemColors]. This enables the corresponding TColor values defined in the <file>graphics.pp</file> unit. By including cbCustomColor in Style, the custom color is stored as the first value in the Colors property.
|
|
</p>
|
|
<p>
|
|
Setting a new value for the property causes the SetColorList method to be called to reload the color names and values.

An application must implement and assign an object procedure using the signature in TGetColorsEvent to respond to the notification. <var>Sender</var> is the <var>TCustomColorBox</var> control for the event notification. <var>Items</var> is the <var>TStrings</var> instance with the existing color names and values stored in the control.
|

</p>
|
|
<p>
|
|
The event handler can perform any actions needed to populate the list of Items. This can include clearing the Items, adding or removing selected names and color values, or using color names and/or values not defined as color constants in the graphics.pp unit. It could also be used to implement a custom color palette with specific pre-defined color combinations.
|
|
</p>
|
|
<p>
|
|
Some common operations:
|
|
</p>
|
|
<p>
|
|
Clear the list of ltems:
|
|
</p>
|
|
<code>Items.Clear;</code>
|
|
<p>
|
|
Add a specific color:
|
|
</p>
|
|
<code>Items.AddObject(rsSkyBlueColorCaption, TObject(PtrInt(clSkyBlue)));</code>
|
|
<p>
|
|
Delete a specific color:
|
|
</p>
|
|
<code>iPos := Items.IndexOf(rsSkyBlueColorCaption);
|
|
if iPos <> -1 then
|
|
Items.Delete(iPos);</code>
|
|
<p>
|
|
OnGetColors is signalled (when assigned) when the color list is loaded for the control, and <var>cbCustomColors</var> has been included in the <var>Style</var> for the control. This occurs when a new value is assigned to the Style property.

DoSelectionChange is an overridden method used to perform actions needed when the value in the ItemIndex property is changed.

The User parameter indicates the origin of the change. When User is <b>True</b>, the change occurred due to user interaction with the control. When User is <b>False</b>, the change occurred when the ItemIndex property was updated by another method in the control.
|

</p>
|
|
<p>
|
|
When User is <b>True</b>, the Style property is examined to see if a custom color can be used in the Colors for the control. When Style includes the value cbCustomColor, and ItemIndex is set to 0, the PickCustomColor method is called to select a custom color using a color dialog. If a custom color was successfully selected, the TColor value in Colors for the ItemIndex is stored in the Selected property.

The color dialog is not displayed, and Selected is not updated when User is set to <b>False</b>.

PickCustomColor is a Boolean function used to select a custom color rather than one of the standard colors in the Colors property.

PickCustomColor is used when cbCustomColor is included in the Style for the control and ItemIndex is set to 0. This position was reserved for a custom color when the list of colors was loaded for the Style settings in the control.

PickCustomColor uses an existing value in ColorDialog when available, or creates and executes a TColorDialog to get the color selection for the control. The custom color selection is stored as the first TColor value in the Items for the control. When a color is successfully selected using the dialog, the return value is set to <b>True</b> and the control is redrawn.

Like <var>clDefault</var>, clNone does not have any meaning without a context where it is applied. Its actual value is different for Forms, Buttons, Windows, etc. This property allows clNone to be resolved to an actual TColor value when needed.
|
|
</p>
|
|
<p>
|
|
The default value for the property is <var>clBlack</var>.
|
|
</p>
|
|
<p>
|
|
Changing the value for the property causes the control to be redrawn.
|
|
</p>
|
|
<p>
|
|
NoneColorColor is used in the <var>DrawItem</var> method to resolve the clNone color constant when drawing items in the control.
|
|
</p>
|
|
<p>
|
|
Use <var>DefaultColorColor</var> for the TColor value used for the <var>clDefault</var> color constant.
|
|
</p>
|
|
<p>
|
|
Use <var>Style</var> to include or exclude the clDefault and clNone color constants in the Colors for the control.

<element name="TCustomColorListBox.OnGetColors">

<short>

<var>OnGetColors</var> - event handler for the instruction to get colors.
|
|
</short>
|
|
<descr>
|
|
<p>
|
|
<var>OnGetColors</var> is a <var>TGetColorsEvent</var> property with the event handler signalled to get custom colors used in the list box control.
|
|
</p>
|
|
<p>
|
|
An application must implement and assign an object procedure using the signature in TGetColorsEvent to respond to the notification. <var>Sender</var> is the <var>TCustomColorBox</var> control for the event notification. <var>Items</var> is the <var>TStrings</var> instance with the existing color names and values stored in the control.
|
|
</p>
|
|
<p>
|
|
The event handler can perform any actions needed to populate the list of Items. This can include clearing the Items, adding or removing selected names and color values, or using color names and/or values not defined as color constants in the graphics.pp unit. It could also be used to implement a custom color palette with specific pre-defined color combinations.
|
|
</p>
|
|
<p>
|
|
Some common operations:
|
|
</p>
|
|
<p>
|
|
Clear the list of ltems:
|
|
</p>
|
|
<code>Items.Clear;</code>
|
|
<p>
|
|
Add a specific color:
|
|
</p>
|
|
<code>Items.AddObject(rsSkyBlueColorCaption, TObject(PtrInt(clSkyBlue)));</code>
|
|
<p>
|
|
Delete a specific color:
|
|
</p>
|
|
<code>iPos := Items.IndexOf(rsSkyBlueColorCaption);
|
|
if iPos <> -1 then
|
|
Items.Delete(iPos);</code>
|
|
<p>
|
|
OnGetColors is signalled (when assigned) when the color list is loaded for the control, and <var>cbCustomColors</var> has been included in the <var>Style</var> for the control. This occurs when a new value is assigned to the Style property.

<var>ColorDialog</var> is a <var>TColorDialog</var> property with the dialog displayed to select a custom color for the control. It can be assigned directly to the control, or it can be created at run-time when the <var>PickCustomColor</var> method is called.

<element name="TColorListBox">

<short>

Implements a list box control used to display and select color names and values.
|
|
</short>
|
|
<descr>
|
|
<p>
|
|
<var>TColorListBox</var> is a <var>TCustomColorListBox</var> descendant which implements a list box control used to display and select color names and values. Each item in the control has a small rectangle where the color is displayed (swatch) and the color name.
|
|
</p>
|
|
<p>
|
|
The <var>Style</var> property is used to configure the list of available colors and their display names. Style may also trigger use of the <var>OnGetColors</var> event handler to get the items displayed in the list box control.
|
|
</p>
|
|
<p>
|
|
The <var>ColorRectWidth</var> and <var>ColorRectOffset</var> properties can be used to control the size and spacing for the color swatch displayed for the list items.
|
|
</p>
|
|
<p>
|
|
<var>Colors</var> allows indexed access to the <var>TColor</var> values in the list of items. When included in the Style property, colors like <var>clDefault</var> and/or <var>clNone</var> may be included in the list of Colors. The <var>DefaultColorColor</var> and <var>NoneColorColor</var> properties can be used to specify the TColor values used for those color constants.
|
|
</p>
|
|
<p>
|
|
ColorNames allows indexed access to the names for the values in Colors.
|
|
</p>
|
|
<p>
|
|
Use <var>TCustomColorBox</var> / <var>TColorBox</var> to display color names and values in a combo-box control.
