Here you used label_style.qml, there is the string labeling/displayAll =
false. It is that i needed, but it not worked for me... :(
bool loadedStyle;
m_layer-loadNamedStyle( path_to_style + /label_style.qml, loadedStyle);
m_layer-setCustomProperty(labeling/fieldName, );
I did refreshing... nothing
Also i tried m_layer-setCustomProperty(labeling/dataDefined/AlwaysShow,
1~~0LblAShow) - nothing too...
It`s strange, why this not work. I looked at QGis sources and tried to do
the same - again nothing... I thing there is something little nuance, but i
don`t know
Solved, but this way is not good, i think :)
layer-startEditing();
QListQgsField fields;
fields.append(QgsField(XCoordinate, QVariant::Double));
layer-addAttribute(QgsField(XCoordinate, QVariant::Double));
fields.append(QgsField(YCoordinate, QVariant::Double));
One more problem: how to disable rendering too many labels (overlapped
labels) ?
I tried this code:
bool inSets = QgsProject::instance()-readBoolEntry(PAL,
/ShowingAllLabels);
QgsPalLabeling* mPal =
(QgsPalLabeling*)m_map-mapCanvas()-mapRenderer()-labelingEngine();
Does anybody knows how to solve this?

We built QGIS-2.0.1 + all deps for Windows7 x64. And when we checked GDAL, we
found that it was built without exif option. After that we rebuilt GDAL -
and all is ok now.

Hi!
I have a problem: how to disable signing of the composite objects in
QgsVectorLayer using Qt?
I can`t find such methods in QgsLabel, QgsVectorLayer or QgsLabelAttributes
classes...
Thanks!

Also i tried this:
QgsPalLayerSettings lyr;
lyr.readFromLayer(m_layer);
lyr.labelPerPart = false;
lyr.writeToLayer(m_layer);
but it now worked too...What i`m doing wrong?

Hi! I can`t change selection color using Qt in my app. Can anybody help with
it?
QgsMapCanvas::mapRenderer()-rendererContext()-setSelectionColor(QColor)
not works :(
P.S. Also it would be awesome if you tell me how to set selection color and
selection border via Qt...
Thanks!

Thanks for answer. But...
QgsFeatureIds ids1;
for(int i = 0; i 5; i++){
layer1-startEditing();
QgsFeature f;
f.setGeometry(QgsGeometry::fromRect(QgsRectangle(i * 10, i * 10, (i +
1) *

f.setValid(true);
layer1-addFeature(f);
Thanks Matthias!

Try this code. When i add feature to layer it says to me that id is negative
and not depend from layer (-2, -3, -4... for first and -6,-7,-8... for
second layer), but feature iterator says that ids are positive (1, 2, 3 ..
for first layer and 1, 2, 3 ... for second layer).
Is this a bug?
What i`m
Please, somebody help me!

Hi!
I write on C++.
Question: how to use QgsCategorizedSymbolRendererV2?
Input data:
1. Some features with unique fields (for example QgsField(id,
QVariant::String))
2. QgsVectorLayer with memory data provider and Polygon items
Task:
I need to draw this features with different colors.
Now i
I have this example, that worked in QGis 1.8 but in QGis 2.0 don`t. What i`m
doing wrong?
QgsFields fields;
fields.append(QgsField(id, QVariant::String, id));
fields.append(QgsField(name, QVariant::String, name));
QgsFeature feature = QgsFeature(fields);
qDebug() Add Attr
I did it! But there are some little bugs.. But idea is right. I was need to
transform degrees to mercator points manually.
Thanks!

Ok, how can i set extent to layers extent?
QgsApplication a(argc,argv, true);
QgsProviderRegistry::instance(/usr/local/lib/qgis/plugins);
a.setPkgDataPath(QDir::homePath() + QDir::separator() + .harver/);
QgsMapCanvas *canvas = new QgsMapCanvas(0, 0);
First of all thanks for reply, Kaosmos
I wrote as you said.
m_mapCanvas-mapRenderer()-setProjectionsEnabled(true);
m_mapCanvas-mapRenderer()-setDestinationCrs(m_mapCanvas-pseudoMercator());
m_mapCanvas-mapRenderer()-setMapUnits(m_mapCanvas-pseudoMercator().mapUnits());
I created custom layer
Hey? Nobody knows how to do this?
