|
Sets the way to display the value.
LABELSLIDER_NORMAL
- Shows the value as a normal number
LABELSLIDER_FRAMENUMBER
- Shows the number as a timecode according to config.timecode_view
. By default, will render hh:mm:ss:ff
LABELSLIDER_PERCENT
- Shows the number as a percentage. 1.0 becomes "100%", 0.5 becomes 50%, etc.
LABELSLIDER_DECIBLE
- Shows the number as a decibel. 1.0 becomes "0 dB", 2.0 becomes roughly "6 dB", 0.5 becomes roughly "-6 dB", etc.
- Parameters
-
type | The display type to set to. |
void LabelSlider::SetFrameRate |
( |
double |
d | ) |
|
Set the display frame rate.
If the display_type
is set to LABELSLIDER_FRAMENUMBER, this function sets how many frames per second the timecode will be in.
- Parameters
-
void LabelSlider::SetMaximum |
( |
double |
v | ) |
|
|
slot |
Set the maximum value.
If a maximum value is set, the value will never go above it. If the user manually sets a value higher than the maximum, it will automatically snap to the maximum.
- Parameters
-
void LabelSlider::SetMinimum |
( |
double |
v | ) |
|

( |
double |
v | ) |
|
Set the value.
- Parameters
-
v | Value to set to. |
userSet | TRUE if this was called through a user action, FALSE if this was called through some other way. The only difference is TRUE will emit a signal (valueChanged()) indicating that the value has changed, and FALSE will not. |
void LabelSlider::ShowContextMenu |
( |
const QPoint & |
pos | ) |
|
|
privateslot |
