xml - KML Linestring plotting problems -


i have xml file coordinates. xml transformed throw xslt file kml file (only placemarks). i've tested on google earth , it's working fine. now, i'm trying use same coordinates use placemarks, in order plot linestring connects placemarks, however, linestring not being correctly plotted, can see in image below. can see, seems linestring going , forward. idea of might be?

linestring

the xslt code i'm using creating linestring following

<style id="rangecolour">             <linestyle><color>660000ff</color><width>1</width></linestyle>             <polystyle><color>660000ff</color></polystyle>         </style>         <style id="linecolour">             <linestyle><color>660000ff</color><width>3</width></linestyle>         </style>         <placemark>             <name>distribution/range</name>             <description></description>             <styleurl>#linecolour</styleurl>             <linestring>                 <tessellate>1</tessellate>                 <altitudemode>clamptoground</altitudemode>                 <coordinates>                     <xsl:for-each select="xs:experience/xs:data/xs:provider">                         <xsl:value-of select="xs:longitude"/>,<xsl:value-of select="xs:latitude"/>,<xsl:value-of select="xs:altitude"/><xsl:text> </xsl:text>                     </xsl:for-each>                 </coordinates>             </linestring>         </placemark>

and resulting kml part linestring following one:

    <style id="rangecolour">   <linestyle>     <color>660000ff</color>     <width>1</width>   </linestyle>   <polystyle>     <color>660000ff</color>   </polystyle> </style> <style id="linecolour">   <linestyle>     <color>660000ff</color>     <width>3</width>   </linestyle> </style> <placemark>   <name>distribution/range</name>   <description/>   <styleurl>#linecolour</styleurl>   <linestring>     <tessellate>1</tessellate>     <altitudemode>clamptoground</altitudemode>     <coordinates>-9.275993,38.757603,210.2     -9.276027,38.757572,228.1     ...     -9.257803,38.75908,159.5     -9.256753,38.75883,159.5     </coordinates>   </linestring> </placemark>

many usefull help.

the linestring drawn in order of coordinates provided, need re-order coordinates linestring drawn how you'd like.

without seeing actual coordinates in kml, guess.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
