Re: [Qgis-user] Fwd: Re: Web client background layer printing
Hi Luca, of course theses layers are now twice in the layer tree. Once in the upper leaf derived from the qgs file and once in the lower "Background Layers" leaf. For user interaction I did some more scripting: If the user toggles visibility of the layer in the upper leaf this toggling is ignored and the corresponding layer is toggled in the lower leaf.

[Qgis-user] Fwd: Re: Web client background layer printing
Hi,
this is the drawback of background layers. They are not layers in the
project.
What I do:
I load the same layers (given they are WMS layers) additionally into the
project (with the same name!) Thus these layers can be printed. To
ensure they are visible when the user clicks on printing I use the
following code (in Customizations.js, ATTENTION: work in progress):
// this is a default function in Customizations.js
function customBeforePrint() {
var myCheckedBackgroundLayer = "";
layerTree.root.lastChild.cascade(
function (n) {
if (n.isLeaf() && n.attributes.checked) {
myCheckedBackgroundLayer = n.text;
}
}
);
if (myCheckedBackgroundLayer != "") {
toggleThematicBackgroundLayer(myCheckedBackgroundLayer, true);
}
}
// this is an additional function I added to Customizations.js
// It scans through the layer tree and as soon as it hits a layer with
// the same name as the currently visible background layer it adds it to
// the visible layers
function toggleThematicBackgroundLayer(layerName, show) {
layerTree.root.firstChild.cascade(
function (n) {
if (n.isLeaf() && n.text == layerName) {
n.getUI().toggleCheck(show);
}
}
);
var myLayers = thematicLayer.params.LAYERS;
if (show) {
myLayers = layerName + "," + myLayers ;
} else {
myLayers.replace(layerName + ",", "");
}
thematicLayer.params.LAYERS = myLayers;
}
good luck
Bernhard

Is it somehow possible to print a web client map with its background layer
visible on the print?
