Control Types Used in Toolbars

In the lower part of the previous picture we see the Controls toolbar toolbar, which contains all kinds of controls that can be used in toolbars.

Control	Description
Push Button	This is a standard push button. When pressed it sends an vpiDomains::e_Menu event to the parent window. The bitmap must be registered for the button.
Check Button	This is used to indicate the state of a property that can have two states; either checked or unchecked. When pressed it sends an vpiDomains::e_Control(_, vpiDomains::wc_CheckBox,_,_) event to the parent window. You must register a bitmap for a check button.
List Button	A list button can be used to select one item from a number of values. When pressed it sends an vpiDomains::e_Control(_, vpiDomains::wc_LBoxButton,_,_) event to the parent window.
Static Text	Text may be placed in this control initially and also dynamically. A Static Text is often used for titles.
Context Sensitive Text	If a Context Sensitive Text field is put into the toolbar, this field will display help information about the control the mouse is currently located over.
Separator	A separator is like a space; it is used to make some space and a vertical bar between other controls, usually to divide them into functional groups.
New Row	New row is relevant only for toolbars with the styles Inside and Movable. A New Row control will cause the current line to break, and the following controls to appear on the next line of the toolbar.

Toolbar Layout Editing

The layout of the toolbar can be done both with the keyboard, and with the mouse. There is an insertion point that is marked with a colored bar. This insertion point can be moved with the arrow keys, or by clicking the mouse on the new location. When the insertion bar is at a given location, the control to the right of the bar can be deleted by pressing the Delete key, the control to the left can be deleted by pressing the Backspace key.

To place a new control at the insertion point:

• select an item from the Controls menu or
• choose a control from the ones shown in the Controls floating dialog or
• click the right mouse button anywhere in the Toolbars Editor window area outside the toolbar to display a pop up from which a desired control can be selected.

Attributes of Toolbar Controls

After a control is inserted, it is possible to change the control attributes. Just double-click the control.

Push and Check Button Attributes

Double-click a Push button or a Check button calls the Button Attributes dialog.

Specifying properties of push buttons and check buttons

The following information must be specified:

Constant	A constant name to identify the button control. This is the constant that will be used in the vpiDomains::e_Menu events. Therefore, it is recommended to use the same constant as is used for the menu item correspondent to the same command. The Constant input box is where you can select or type in the symbolic constant that will be used as the control identifier. It can be input directly from the keyboard or selected from the list of available constants (by clicking the button). It must be either a legal symbolic constant (for example, idt_file_open ) or an integer value. If you enter a symbolic constant, then the IDE automatically places this symbolic constant into the resourceidentifiers.i file and generates an appropriate integer value for it. The Toolbar Editor automatically generates the default symbolic constants (for example, idt_7 from the toolbar constant prefix idt_ and the number of this control in the toolbar.
Status Text	The string entered into this field can consist from 2 sub-strings separated by a semicolon. The sub-string specified before the semicolon (if specified) is used as the button Tool Tip text. The sub-string specified after the semicolon (or if the semicolon is not specified) will be displayed in the Context Sensitive Text field (when the mouse cursor is positioned over this button). For example, the text New;New file will cause New to be shown in the yellow tool tip while New file will be shown in a context sensitive field when the mouse is over the button.
Checked	If this check box is checked than the button initial state is "pressed" and the icon shaped as pressed is initially displayed. Otherwise the button initial state is "released" and the icon shaped as released is displayed.
Disabled	If this check box is checked then the button initially does not accept a user input and is grayed. Otherwise the button is initially enabled (accepts a user input) and has initial state specified by the Checked check box.
Push Button or Check Button	Select the appropriate button style (Push Button or Check Button). The style can be changed at any time. At runtime the state (pressed or released) of a check button can be switched by clicking the check button.
Bitmap Name	This bitmap will be used to display a button. This bitmap should be selected from the list of bitmaps registered in the Project window (by clicking the button). Before a bitmap name will appear in the registered bitmap list, it should be registered in the project with the File | Add command (the Resource Files should be selected in the Files of Type). In Visual Prolog v.7 we use a single bitmap for each button and automatically draw different state ornamentations for the released state, the pressed state, and the disabled state of the button.
Edit	If the Edit button is pressed, then the Graphics Editor will come up with the given bitmap allowing you to view and edit the bitmap.

Text Control Attributes

Double-clicking a Static Text or a Context Sensitive Text control calls the Text Attributes dialog:

Specifying properties of text controls in a toolbar

The following information must be specified:

Constant	A constant name to identify the Text control.
Initial Text	The default text to display in the field.
Static or Context Sensitive	Select the appropriate text control type. The style can be changed at any time.
Font	Select a font name, font style (Normal, Bold, Italic ...), and font size for the displayed text.
Text Width	Determines a width in pixels of the Text control field. It can be entered manually or, by pushing the "|<---Text--->|" button. In this case the width of the field will be optimized to display the Initial Text with the selected Font.
Foreground Color	Select the Foreground Color for the displayed text.

List Button Attributes

Double-clicking a List Button control calls the List Button Attributes dialog.

Specifying properties of list buttons in a toolbar

Only two parameters can be set for a list button in a toolbar:
