c4d.gui.GeUserArea¶

class c4d.gui.GeUserArea¶

This class helps you to create custom gadgets for dialogs in Cinema 4D.

Note

Just take care about the lifetime of your GeUserArea instance.
If you pass an instance of this class to a dialog, a reference is hold by the dialog and released when the dialog is freed.
That also means that each instance of your GeUserArea class is still alive until the host-dialog is freed, even you dont hold a reference to it.
If you want to use the same instance of your GeUserArea class on the next time you open the dialog, you have to store the instance in the class scope.
See the geuserarea_basic_r13.py example.

The class to create custom user areas.

Parameters: msg (c4d.BaseContainer) – The message container.
Returns: Return the result of the message.
Return type: Any

GeUserArea.SetTimer(self, x)¶

Initializes the timer clock, so that Timer() is called every timer milliseconds.

Note

Depending on the speed of the computer, the operating system, the complexity of the dialog and the threads running in the background, there is no guarantuee that event messages will occur on a regular basis.

Using a value of 500 ms should be no problem but if using a value of 1 ms one might get events with the following time spaces: 3 ms, 76 ms, 15 ms, 19 ms, 67 ms…

Note

Keep in mind that using small timer values results in heavy message traffic in the application which may slow down Cinema 4D (and all other applications running on the computer) to a point where nothing is working any longer besides your dialog.

Parameters: x (int) – The timer interval in milliseconds.

GeUserArea.OffScreenOn(self, x=NOTOK, y=0, w=0, h=0)¶

Enables double buffering to avoid blinking and flickering effects.
Sets the clipping area to the rectangular area determined by x, y, w and h.
If x == c4d.NOTOK the size will be calculated automatically.

Note

The GUI will automatically switch planes.

Note

Just call this function before drawing things.

Parameters

x (int) – X-coordinate of the clipping area.
y (int) – Y-coordinate of the clipping area.
w (int) – Width of the clipping area.
h (int) – Height of the clipping area.

Return type

bool

Returns

Should be used at the top of the DrawMsg() function to specify the clipping region.

Without specifying a dedicated clipping region everything will be painted, even if it is outside the user area!

Note

The method OffScreenOn() automatically sets the clipping region to the whole user area, so normally this function is not necessary.

Parameters

x (int) – X coordinate of the upper left corner of the clipping region.
y (int) – Y coordinate of the upper left corner of the clipping region.
w (int) – Width of the clipping region.
h (int) – Height of the clipping region.

New in version R14.014.

Note

Due to improve speed performance, the elements of p will be modified and might be invalid and all values must be set again if DrawBezier() will be called again with the same array.

Parameters

sx (float) – X coordinate of the upper left corner of the drawn curve. This is the X coordinate of the starting point.
sy (float) – Y coordinate of the upper left corner of the drawn curve. This is the Y coordinate of the starting point.

p (List[float]) –

An array with the bezier curves points.

Here is an example of initializing the curve points array.

points = array.array('f', range(6))

points[0] = 35  # The X coordinate of the control point for the starting point.
points[1] = 200 # The Y coordinate of the control point for the starting point.
points[2] = 220 # The X coordinate of the control point for the ending point.
points[3] = 260 # The Y coordinate of the control point for the ending point.
points[4] = 220 # The X coordinate of the ending point.
points[5] = 40 # The Y coordinate of the ending point.

self.DrawBezier(120, 160, points, False, False)

closed (bool) – If True, the last point of the last segment connects back to the starting point ( sx , sy).
filled (bool) – If True, fills the drawn bezier curves, only if it is also closed.

GeUserArea.DrawBezierFill(self, startPoint, bezierPoints, closed)¶

Draws concatenated Bezier curves.

New in version R25.010.

Here is an example of initializing the curve points array.

Note

To define the line segment, you have to introduce three points, two handle and one end point. Each point is defined by two float, so the length of the bezierPoint should be a multiple of six. Handle’s coordinates must be set within the GeUserArea space coordinate.

points = array.array('f', range(6))

points[0] = 35  # The X coordinate for the starting point's handle.
points[1] = 200 # The Y coordinate for the starting point's handle.
points[2] = 220 # The X coordinate for the ending point's handle.
points[3] = 260 # The Y coordinate for the ending point's handle.
points[4] = 220 # The X coordinate of the ending point.
points[5] = 40 # The Y coordinate of the ending point.

self.DrawBezierLine(120, 160, points, False, False)

closed (bool) – If True, the last point of the last segment connects back to the starting point ( sx , sy).
