CG tab on Options dialog

This tab of the Options dialog groups together the options that affect not only the IDE, as the options on all of the tabs do, but also affect standalone Common Graphics applications. (In addition to the options on this tab, the two buttons on the Fonts tab for fixed-font and proportional-font can affect Common Graphics apps as well.) In a standalone Common Graphics app, you would use an expression such as:

(setf (show-tooltips (configuration *system*)) nil)

to turn off all tooltips in your application entirely, for example. (To change a different property, replace show-tooltips with the desired property generic function.)

The Default Window Sizes Group. The options here allow you to specify the sizes used when a window is created without specified dimensions.

• Width Factor: if checked, a positive real value can be specified in the editable-text box to the right. The width of the new window will be this fraction of the width of its parent. Ignored if a non-nil is specified for Width below. See default-width-factor.
• Height Factor: if checked, a positive real value can be specified in the editable-text box to the right. The height of the new window will be this fraction of the height of its parent. Ignored if a non-nil is specified for Height below. See default-height-factor.
• Width: if checked, a positive integer can be specified in the editable-text box to the right. The width of the new window will be this number of pixels. See default-width.
• Height: if checked, a positive integer can be specified in the editable-text box to the right. The height of the new window will be this number of pixels. See default-height.

The Tooltips Group. The options here allow you to specify tooltip behavior.

• Show Tooltips: if checked, tooltips will be used. See show-tooltips.
• Tooltip Delay: the value in the editable-text box to the right is the number of milliseconds before a tooltip is displayed. See tooltip-delay.
• Tooltip Vertical Offset: the value in the editable-text box to the right is the number of pixels a tooltip is offset in the vertical direction from the object being described. See tooltip-vertical-offset.
• Menu Tooltip Delay: the value in the editable-text box to the right is the number of milliseconds before a tooltip for a menu-item is displayed. (Menu-item help-strings are displayed as tooltips if the show-help-strings-as-tooltips property of a pull-down menu is true.) See menu-tooltip-delay.

The other items on the dialog are:

• Offset from Selected Window: if checked, a new window is created by default with its top-left corner near the top-left corner of the window that is currently selected on the owner window (or screen) of the new window. If there is no such selected window, then the upper left corner of the owner window (or screen) is used. See offset-from-selected-window.
• Center All Modal Dialogs on Screen: Changes the value of center-all-modal-dialogs-on-screen.
• Modal Dialog Margin: the offset from the top-left of the inner box of the window active when a modal dialog is displayed, if Center All Modal Dialogs on Screen is nil. See modal-dialog-margin.
• Multipic Scroll Interval: the number of milliseconds between successive scroll increments of a multi-picture-button as the mouse button is held down after clicking a multi-picture-button scroll arrow. See multi-picture-button-scroll-interval.
• Custom Tooltip Font: allows choosing a custom-tooltip-font. The default for that property is nil. If the value has been changed to a font object, clicking on the button will first display a dialog asking if you want to revert to the default, and only display a font choice dialog if you answer no.
• Custom Status Bar Font: allows choosing a custom-status-bar-font. The default for that property is nil. If the value has been changed to a font object, clicking on the button will first display a dialog asking if you want to revert to the default, and only display a font choice dialog if you answer no.
