[Qgis-developer] QGIS crash sometimes damages project file
Hi, I had it now the second time that a crashing QGIS would damage a project file. Unfortunately it wasn't myself, but co-workers of me and I did not exactly see what they did. According to the users they did not even save the project, just QGIS crashed and destroyed the .qgs file. Can this really happen? I examined the .qgs-File after the crash, the file was still well-formed, but the legend/ element was empty, all the print composers disappeared and several map layers were missing. Is this a known-issue? For now, I set the project-file to read-only to avoid such problems so that only I as the administrator can modify the file, but it is not the best solution ... - From my wife I also heard that some of her students had this issue of broken .qgs files after QGIS crashes. So at least this is not only in our office. - I am really sorry that I cannot provide more details now. Just want to see if others have similar issues and if there are solutions.

Re: [Qgis-developer] Reliable way to determine a groupIndex in the legend tree
Etienne, I was not opposing your idea. Just proposing a default behavior for the group/children visibility pattern. I sometimes do have need for your use case. Maybe there could be an option in the context menu when right-clicking a layer - eg Mutually exclusive layers. A popup window could appear that allows you to select the 2 opposing collections of layers, and then these could appear with a radio button in the maplegend.

You should have a modifier to get this as a secondary behavior, like pressing the ctrl key when (un)checking the group checkbox. The primary behavior of the group switch should be to make the children invisible or visible, regardless of the children's visibility being on or off. In the primary behavior when the parent is turned OFF, the children are not drawn but retain their checked or uncheck status. If you use the secondary behavior then unchecking the parent will uncheck the children. Same would apply when checking the parent on. Agreed, sounds like a sensible behavior to me. Yes, a sensible behavior. But there is still use-case for the radio-button like behaviour. Imagine having a group with a series of orthoimages of different years and you quickly want to see each year. In this case, the radio-button behaviour would save you one click. So I don't think that this contradicts the other proposal listed above here. Maybe this could be obtained with secondary behavior (SHIFT-click) on layers, but it sounds like something that easily becomes confusing (conflicting with radio-on-groups, undefined behavior for unchecking etc.). switching between several raster layers is exactly the main (only) use I have for this, and as we are mainly doing remote sensing stuff here, including lots of time series, it is something I really frequently miss. (Practical example: you have several Landsat rasters from different times for the same area, all of them have clouds but not in the same place. By switching between layers, you can easily get a 'cloudfree' view of the entire area.) I have made the Loop Visible Layers plugin for just that. Add the reaster layers you want to see in a group, then select that group in the Loop Visible Layers dock and click play. You will see those raster layers one at a time. IMHO 'undefined behavior for unchecking' should not be a problem; usually unchecking simply is disabled for radio groups. I do not know any UI with radio groups where you can uncheck a selected item by clicking it again... I think having it as a secondary behaviour is just confusing. I'd rather see groups have a 'selection type' property, which defines the selection behaviour within that group (and on that level only). Could you explain what you mean with 'conflicting with radio-on-groups' (what are 'radio-on-groups')?

[Qgis-developer] how to add labels to PluginLayer? - please help!
Hi,
Apparently no one is to help me... I found it is not simply possible to put
labels at where I want on the plugin layer. Apparently no one is using
QGsLabel
anymore, and documentation is missing or obscure...
Qgis keeps crashing on me when I try to add label in python, which I
believe is a bug
anyway.
Regards,
Mikhail
Original post:
Hi,
I am trying to add labels to the plugin layer. What I use in draw()
is:
fields = QgsFields()
fields.append(QgsField('0', QtCore.QVariant.String, 'string', 32))
fields.append(QgsField('8', QtCore.QVariant.Double, 'double', 8))
fields.append(QgsField('9', QtCore.QVariant.Double, 'double', 8))
feat = QgsFeature(fields)
label = QgsLabel(fields)
feat.setAttribute('0','Test Text')
feat.setAttribute('8', -8.66774)
feat.setAttribute('9', 37.08391)
label.renderLabel(renderContext, feat, False)
- QGIS crashes (2.0.1, stock version, Linux)
There is almost no doc on how to add labels to the layer
I am trying to mimic field 'Text' 'XCoordinate' and 'YCoordinate'
with '0', '8' and '9' based on enum LabelField
Apparently also some change in the Api since 1.8, I was
using GridPlugin from 1.8 as example, but something is different now.
Could anyone shed some light on it?
I am actually developing Lat/Lon grid plugin for QGIS, which I think
very much needed.

Re: [Qgis-developer] how to add labels to PluginLayer? - please help!
It appeared that I made it work. It might be not the best way,but it works.
It also might get outdated as new labeling engine being developed.
1. In the __init__ I add:
self.fields = QgsFields()
self.label = QgsLabel(self.fields)
Not sure I need to keep object QgsLabel but I do.
Also self.fields are actually not used, this is just requirement
for QgsLabelconstructor
2. In the function to draw label:
# again, fields has nothing inside
fields = QgsFields()
feat = QgsFeature(fields)
# init number of attributes with the same number of fields
# as enum LabelFields in the QgsLabel class
# this is just for convenience and is not very nice
feat.initAttributes(QgsLabel.LabelFieldCount)
# set feature geometry as a point. Here x,y is position of the label
feat.setGeometry(QgsGeometry.fromPoint(QGpsPoint(x,y)))
# now we have two options to set label options: or we use
# label itself or we use feature feat It is better to use label itself
# for font, color etc if we draw bunch of labels. Here is how can be done:
# ( example from my dialog)
self.label.labelAttributes().setFamily(self.dlg.label_attributes.family())
self.label.labelAttributes().setBold(self.dlg.label_attributes.bold())
self.label.labelAttributes().setItalic(self.dlg.label_attributes.italic())
self.label.labelAttributes().setUnderline(self.dlg.label_attributes.underline())
self.label.labelAttributes().setStrikeOut(self.dlg.label_attributes.strikeOut())
self.label.labelAttributes().setSize(self.dlg.label_attributes.size(),
core.QgsLabelAttributes.PointUnits)
self.label.labelAttributes().setColor(QtGui.QColor.fromRgba(self.dlg.label_attributes.color().rgba()))
# the rest of the attribute we set using feature feat
# note that above call feat.initAttributes(QgsLabel.LabelFieldCount)is
# essential for to allow setting these attributes as below
feat.setAttribute(QgsLabel.Angle,90.)
feat.setAttribute(QgsLabel.Alignment, 'right')
# etc. Noe that now we need to tell QgsLabel where to search for the
attributes.
# Because we created the same number of feature attributes as size of
enum LabelField
# we can tell it this way:
self.label.setLabelField(QgsLabel.Text,QgsLabel.Text)
self.label.setLabelField(QgsLabel.Angle,QgsLabel.Angle)
self.label.setLabelField(QgsLabel.Alignment,QgsLabel.Alignment)
# Note that first and second argument is the same but this is only
# because number of feature attributes was set the same as LabelField size.
# many of the attributes this way remain unset.
# note that you also can specify font, color etc using
self.label.setLabelField()
# finally draw the labels. I used function drawLabels(self, renderContext)
# Just add:
self.label.renderLabel(renderContext, feat, False)

Hi,
Apparently no one is to help me... I found it is not simply possible
to put
labels at where I want on the plugin layer. Apparently no one is using
QGsLabel
anymore, and documentation is missing or obscure...
Qgis keeps crashing on me when I try to add label in python, which I
believe is a bug
anyway.

Original post:
Hi,
I am trying to add labels to the plugin layer. What I use in draw()
is:
fields = QgsFields()
fields.append(QgsField('0', QtCore.QVariant.String, 'string', 32))
fields.append(QgsField('8', QtCore.QVariant.Double, 'double', 8))
fields.append(QgsField('9', QtCore.QVariant.Double, 'double', 8))
feat = QgsFeature(fields)
label = QgsLabel(fields)
feat.setAttribute('0','Test Text')
feat.setAttribute('8', -8.66774)
feat.setAttribute('9', 37.08391)
label.renderLabel(renderContext, feat, False)
- QGIS crashes (2.0.1, stock version, Linux)
There is almost no doc on how to add labels to the layer
I am trying to mimic field 'Text' 'XCoordinate' and 'YCoordinate'
with '0', '8' and '9' based on enum LabelField
Apparently also some change in the Api since 1.8, I was
using GridPlugin from 1.8 as example, but something is different now.
Could anyone shed some light on it?
I am actually developing Lat/Lon grid plugin for QGIS, which I think
very much needed.
Thank you
Mikhail
