Event ID

Menu


Arguments

None

Return Values

None (do not use a RETURN statement)

Usage

If the user highlights the menu item without choosing it, its Selected event occurs.

If the user chooses a menu item that has a cascaded menu associated with it, the Clicked event occurs, and the cascaded menu is displayed.

Examples

This script is for the Clicked event of the New menu item for the frame window. The wf_newsheet function is a window function. The window w_genapp_frame is part of the application template you can generate when you create a new application:

/* Create a new sheet */
w_genapp_frame.wf_newsheet( )

Event ID

Event ID

Objects

pbm_lvnclicked

ListView


Arguments

Argument

Description

index

Integer by value (the index of the ListView item the user clicked). The value of index is -1 if the user clicks within the control but not on a specific item.


Return Values

Long.

Return code choices (specify in a RETURN statement):

0 -- Continue processing

Usage

The Clicked event occurs when the user presses the mouse button. The Clicked event can occur during a double-click, in addition to the DoubleClicked event.

In addition to the Clicked event, ItemChanging and ItemChanged events can occur when the user clicks on an item that does not already have focus. BeginLabelEdit can occur when the user clicks on a label of an item that has focus.

Using the ItemActivate event for ListView controls

You can use the ItemActivate event (with the OneClickActivate property set to true) instead of the Clicked event for ListView controls.

Examples

This code changes the label of the item the user clicks to uppercase:

IF index = -1 THEN RETURN 0
 
This.GetItem(index, llvi_current)
llvi_current.Label = Upper(llvi_current.Label)
This.SetItem(index, llvi_current)
RETURN 0

Arguments

Argument

Description

index

Integer by value (the index of the tab page the user clicked)


Return Values

Long.

Return code choices (specify in a RETURN statement):

Usage

The Clicked event occurs when the mouse button is released.

When the user clicks in the display area of the Tab control, the tab page user object (not the Tab control) gets a Clicked event.

The Clicked event can occur during a double-click, in addition to the DoubleClicked event.

In addition to the Clicked event, the SelectionChanging and SelectionChanged events can occur when the user clicks on a tab page label. If the user presses an arrow key to change tab pages, the Key event occurs instead of Clicked before SelectionChanging and SelectionChanged.

Examples

This code makes the tab label bold for the fourth tab page only:

IF index = 4 THEN 
   This.BoldSelectedText = TRUE
ELSE
   This.BoldSelectedText = FALSE
END IF

Arguments

Argument

Description

flags

UnsignedLong by value (the modifier keys and mouse buttons that are pressed).

Values are:

  • 1 -- Left mouse button

  • 2 -- Right mouse button (windows only)

  • 4 -- Shift key

  • 8 -- Ctrl key

  • 16 -- Middle mouse button (windows only)

In the Clicked event for windows, the left mouse button is being released, so 1 is not summed in the value of flags.

For an explanation of flags, see Syntax 2 of MouseMove.

xpos

Integer by value (the distance of the pointer from the left edge of the window workspace or control in pixels).

ypos

Integer by value (the distance of the pointer from the top of the window's workspace or control in pixels).


Return Values

Long.

Return code choices (specify in a RETURN statement):

0 -- Continue processing

Usage

The Clicked event occurs when the user presses the mouse button down in progress bars and when the user releases the mouse button in windows.

If the user clicks on a control or menu in a window, that object (rather than the window) gets a Clicked event. No Clicked event occurs when the user clicks the window's title bar.

When the user clicks on a window, the window's MouseDown and MouseUp events also occur.

When the user clicks on a visible disabled control or an invisible enabled control, the window gets a Clicked event.

Examples

If the user clicks in the upper left corner of the window, this code sets focus to the button cb_clear:

IF (xpos <= 600 AND ypos <= 600) THEN
   cb_clear.SetFocus( )
END IF
