    <p>I have a problem using a function when there should not be any problem. In Go, a Function that starts with a capital letter has a visibility outside the package.</p> <hr> <h2>node.go</h2> <pre><code>package grid type Node struct { id uint name string pos_i uint pos_j uint node_type string } </code></pre> <h2>grid.go</h2> <pre><code>package grid /*~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ the Grid Structure ____________________________________________________________________________ */ type Grid struct { // The numbers of divisions in the Grid number_lines uint number_columns uint // The Sizes of the Grid width uint height uint // An Array of the Nodes nodes []Node } /*~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Initialize the Grid ____________________________________________________________________________ */ func InitGrid() *Grid { g := new(Grid) g.number_lines = 4 g.number_columns = 4 g.width = 400 g.height = 400 return g } </code></pre> <h2>main.go</h2> <pre><code>package main import ( "fmt" "grid" ) /*~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Entry Point of the Application ____________________________________________________________________________ */ func main() { grid_ := grid.InitGrid() fmt.Println(grid_) } </code></pre> <hr> <h2>src/grid/Makefile</h2> <pre><code>include $(GOROOT)/src/Make.inc TARG=grid GOFILES=\ node.go\ grid.go\ include $(GOROOT)/src/Make.pkg </code></pre> <h2>src/main/Makefile</h2> <pre><code>include $(GOROOT)/src/Make.inc TARG=main GOFILES=\ main.go\ include $(GOROOT)/src/Make.cmd </code></pre> <hr> <p>When I compile the grid package, everything goes well, but when I try to compile le main package, it gives me that error message:</p> <pre><code>manbear@manbearpig:~/Bureau/go_code/main$ gomake 6g -o _go_.6 main.go main.go:15: undefined: grid.InitGrid make: *** [_go_.6] Erreur 1 </code></pre> <p>I don't understand why it gives me that error, I've passed some time reading the Go documentation, but I don't find the reason why it doesn't work.</p> <p>Thank you for your help.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
