Creating a toolbar button¶

In [2]:

widget_width = "250px"
padding = "0px 0px 0px 5px"  # upper, right, bottom, left

toolbar_button = widgets.ToggleButton(
    value=False,
    tooltip="Toolbar",
    icon="wrench",
    layout=widgets.Layout(width="28px", height="28px", padding=padding),
)

close_button = widgets.ToggleButton(
    value=False,
    tooltip="Close the tool",
    icon="times",
    button_style="primary",
    layout=widgets.Layout(height="28px", width="28px", padding=padding),
)

In [3]:

toolbar = widgets.HBox([toolbar_button])
toolbar

Adding toolbar event¶

In [4]:

def toolbar_click(change):
    if change["new"]:
        toolbar.children = [toolbar_button, close_button]
    else:
        toolbar.children = [toolbar_button]
        
toolbar_button.observe(toolbar_click, "value")

In [5]:

def close_click(change):
    if change["new"]:
        toolbar_button.close()
        close_button.close()
        toolbar.close()
        
close_button.observe(close_click, "value")
toolbar

Adding toolbar grid¶

In [6]:

rows = 2
cols = 2
grid = widgets.GridspecLayout(rows, cols, grid_gap="0px", layout=widgets.Layout(width="62px"))

icons: https://fontawesome.com/v4.7.0/icons/

In [7]:

icons = ["folder-open", "map", "info", "question"]

for i in range(rows):
    for j in range(cols):
        grid[i, j] = widgets.Button(description="", button_style="primary", icon=icons[i*rows+j], 
                                    layout=widgets.Layout(width="28px", padding="0px"))
grid

In [8]:

toolbar = widgets.VBox([toolbar_button])

In [9]:

def toolbar_click(change):
    if change["new"]:
        toolbar.children = [widgets.HBox([close_button, toolbar_button]), grid]
    else:
        toolbar.children = [toolbar_button]
        
toolbar_button.observe(toolbar_click, "value")
toolbar

Adding toolbar to ipyleaflet¶

In [10]:

toolbar_ctrl = WidgetControl(widget=toolbar, position="topright")

In [11]:

m = geodemo.Map()
m.add_control(toolbar_ctrl)
m

In [12]:

output = widgets.Output()
output_ctrl = WidgetControl(widget=output, position="bottomright")
m.add_control(output_ctrl)

In [13]:

def tool_click(b):    
    with output:
        output.clear_output()
        print(f"You clicked the {b.icon} button")

In [14]:

for i in range(rows):
    for j in range(cols):
        tool = grid[i, j]
        tool.on_click(tool_click)
