Move PowerScript function
Description
Moves a control or object to another position relative to
its parent window, or for some window objects, relative to the screen.
Controls
Any object or control
Syntax
|
1 |
<span>objectname</span>.<span>Move</span> ( <span>x</span>, <span>y</span> ) |
|
Argument |
Description |
|---|---|
|
objectname |
The name of the object or control you |
|
x |
The x coordinate of the new location |
|
y |
The y coordinate of the new location |
Return Values
Integer. Returns 1 if it succeeds and
-1 if an error occurs or if objectname is a maximized
window. If any argument’s value is null, Move returns null.
Usage
The x and y coordinates you specify are the new coordinates
of the upper-left corner of the object or control. If the shape
of the object or control is not rectangular (such as, a RadioButton
or Oval), x and y are the coordinates of the upper-left corner of
the box enclosing it. For a line control, x and y
are the BeginX and BeginY properties.
When you move controls, drawing objects, and child windows,
the coordinates you specify are relative to the upper-left corner
of the parent window. When you use Move to position
main, pop-up, and response windows, the coordinates you specify
are relative to the upper-left corner of the display screen.
Move does not move a maximized sheet or window. If the window
is maximized, Move returns –1.
You can specify coordinates outside the frame of the parent
window or screen, which effectively makes the object or control
invisible.
To draw the image of a Picture control at a particular position,
without actually moving the control, use the Draw function.
The Move function changes the X and Y properties
of the moved object.
Equivalent syntax
The syntax below directly sets the X and Y properties of an
object or control. Although the result is equivalent to using the Move function,
it causes PowerBuilder to redraw objectname twice,
first at the new location of X and then at the new X and Y location:
|
1 |
<span>objectname</span>.<span>X</span> = <span>x</span> |
|
1 |
<span>objectname</span>.<span>Y</span> = <span>y</span> |
These statements cause PowerBuilder to redraw gb_box1 twice:
|
1 |
gb_box1.X = 150 |
|
1 |
gb_box1.Y = 200 |
This statement has the same result but redraws gb_box1 once:
|
1 |
gb_box1.<span>Move</span>(150,200) |
Examples
This statement changes the X and Y properties of gb_box1 to
150 and 200, respectively, and moves gb_box1 to
the new location:
|
1 |
gb_box1.<span>Move</span>(150, 200) |
This statement moves the picture p_Train2 next
to the picture p_Train1:
|
1 |
P_Train2.<span>Move</span>(P_Train1.X + P_Train1.Width, & |
|
1 |
P_Train1.Y) |
