◆ DEFAULT_HIGHLIGHT_BUFFER_MM
const double Qgis::DEFAULT_HIGHLIGHT_BUFFER_MM = 0.5 |
|
static |
Default highlight buffer in mm.
- Since
- QGIS 2.3
Definition at line 126 of file qgis.h.
◆ DEFAULT_HIGHLIGHT_COLOR
const QColor Qgis::DEFAULT_HIGHLIGHT_COLOR = QColor( 255, 0, 0, 128 ) |
|
static |
Default highlight color.
The transparency is expected to only be applied to polygon fill. Lines and outlines are rendered opaque.
- Since
- QGIS 2.3
Definition at line 121 of file qgis.h.
◆ DEFAULT_HIGHLIGHT_MIN_WIDTH_MM
const double Qgis::DEFAULT_HIGHLIGHT_MIN_WIDTH_MM = 1.0 |
|
static |
Default highlight line/stroke minimum width in mm.
- Since
- QGIS 2.3
Definition at line 131 of file qgis.h.
◆ DEFAULT_MAPTOPIXEL_THRESHOLD
const float Qgis::DEFAULT_MAPTOPIXEL_THRESHOLD = 1.0f |
|
static |
Default threshold between map coordinates and device coordinates for map2pixel simplification.
Definition at line 115 of file qgis.h.
◆ DEFAULT_SEARCH_RADIUS_MM
const double Qgis::DEFAULT_SEARCH_RADIUS_MM = 2. |
|
static |
Identify search radius in mm.
- Since
- QGIS 2.3
Definition at line 112 of file qgis.h.
◆ DEFAULT_SNAP_TOLERANCE
const double Qgis::DEFAULT_SNAP_TOLERANCE = 12.0 |
|
static |
Default snapping distance tolerance.
- Since
- QGIS 3.0
Definition at line 157 of file qgis.h.
◆ DEFAULT_SNAP_UNITS
Default snapping distance units.
- Since
- QGIS 3.0
Definition at line 163 of file qgis.h.
◆ DEFAULT_Z_COORDINATE
const double Qgis::DEFAULT_Z_COORDINATE = 0.0 |
|
static |
Default Z coordinate value for 2.5d geometry This value have to be assigned to the Z coordinate for the new 2.5d geometry vertex.
- Since
- QGIS 3.0
Definition at line 144 of file qgis.h.
◆ QGIS_DEV_VERSION
const char * Qgis::QGIS_DEV_VERSION = QGSVERSION |
|
static |
The development version.
Definition at line 69 of file qgis.h.
◆ QGIS_RELEASE_NAME
const QString Qgis::QGIS_RELEASE_NAME |
|
static |
Release name.
Definition at line 67 of file qgis.h.
◆ QGIS_VERSION
const QString Qgis::QGIS_VERSION |
|
static |
Version string.
Definition at line 63 of file qgis.h.
◆ QGIS_VERSION_INT
const int Qgis::QGIS_VERSION_INT = VERSION_INT |
|
static |
Version number used for comparing versions using the "Check QGIS Version" function.
Definition at line 65 of file qgis.h.
◆ SCALE_PRECISION
const double Qgis::SCALE_PRECISION = 0.9999999999 |
|
static |
Fudge factor used to compare two scales.
The code is often going from scale to scale denominator. So it looses precision and, when a limit is inclusive, can lead to errors. To avoid that, use this factor instead of using <= or >=.
- Since
- QGIS 2.15
Definition at line 138 of file qgis.h.
◆ UI_SCALE_FACTOR
const double Qgis::UI_SCALE_FACTOR = 1 |
|
static |
UI scaling factor.
This should be applied to all widget sizes obtained from font metrics, to account for differences in the default font sizes across different platforms.
- Since
- QGIS 3.0
