I have finally managed to mock up a selectable grid control (see
http://mumbai.geology.wisc.edu/test/svg_grid.html). The pseudocode is as follows
// create styleMap
var myStyles = new OpenLayers.StyleMap...
// create and add grid_layer
var grid_layer = new OpenLayers.Layer.Vector("Grid", {styleMap: myStyles});
map.addLayer(grid_layer);
// create grid cells
var cells = [];
for (var r = 0; r < rows; r++) {
for (var c = 0; c < cols; c++) {
...
}
}
// add the cells to the grid_layer
grid_layer.addFeatures(cells);
// add and activate highlight and select controls
I have the following questions:
1. Seems like I am unable to make the grid line thinner. I have set
strokeWidth: 1, but it looks rather thick. Can I make it thinner?
2. I want the grid to remain the same size whether I zoom in or out. Do I have
to destroy the layer and re-make it on every map change, resize, etc.?
3. "double-click to zoom", "press shift and drag to zoom", or "click-hold and
drag to pan" are no longer possible because selectControl takes over. Is there
a way to accomplish both?
And, the over-arching question
0. Is there a better way to accomplish all this?
Many thanks in advance for your suggestions,
