    <p>I have this code containing a button called <code>bbutton</code> which when pressed executes the <code>movetext</code> function:</p> <pre><code>from pylab import * from matplotlib.widgets import RectangleSelector from matplotlib.widgets import Button import numpy as np import matplotlib.pylab as plt fig = plt.figure() ax = fig.add_subplot(111) delta = 0.025 x = np.arange(-3.0, 3.0, delta) y = np.arange(-2.0, 2.0, delta) X, Y = np.meshgrid(x, y) Z1 = bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0) Z2 = bivariate_normal(X, Y, 1.5, 0.5, 1, 1) Z = (Z1 - Z2) * 10 plt.contourf(X, Y, Z) text1=plt.text(0, 0, 'ghghg',color='black',fontsize=14) plt.text(1, 1, 'Calculation ',color='black',fontsize=14) plt.title('Average ') plt.xlabel('Longtitude ', fontsize=14, color='black') plt.ylabel('Latitude ', fontsize=14, color='black') plt.grid(True) def onselect(eclick, erelease): 'eclick and erelease are matplotlib events at press and release' text1.set_text('Geo ') text1.set_x(eclick.xdata) text1.set_y(eclick.ydata) plt.draw() def toggle_selector(event): print ' Key pressed.' if event.key in ['Q', 'q'] and toggle_selector.RS.active: print ' RectangleSelector deactivated.' toggle_selector.RS.set_active(False) if event.key in ['A', 'a'] and not toggle_selector.RS.active: print ' RectangleSelector activated.' toggle_selector.RS.set_active(True) def movetext(self): print 'clearing plot' text1.set_x(np.random.random(1)) text1.set_y(np.random.random(1)) plt.draw() toggle_selector.RS = RectangleSelector(ax, onselect, drawtype='line') plt.connect('key_press_event', toggle_selector) buttonaxe = plt.axes([0.7, 0.05, 0.1, 0.1]) bbutton = Button(buttonaxe, 'movetext',color='0.85', hovercolor='0.95') bbutton.on_clicked(movetext) plt.show() </code></pre> <p>The button placed at the bottom works fine. But in the following example if i just put all the code inside a function called <code>Plotter</code> the button shows up in the plot but it is not working. No change when the mouse hovers above the button, and the connected function <code>movetext</code> is not executing.</p> <pre><code>from pylab import * from matplotlib.widgets import RectangleSelector from matplotlib.widgets import Button import numpy as np import matplotlib.pylab as plt fig = plt.figure() ax = fig.add_subplot(111) def Plotter(): delta = 0.025 x = np.arange(-3.0, 3.0, delta) y = np.arange(-2.0, 2.0, delta) X, Y = np.meshgrid(x, y) Z1 = bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0) Z2 = bivariate_normal(X, Y, 1.5, 0.5, 1, 1) Z = (Z1 - Z2) * 10 #Z1 = mlab.bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0) plt.contourf(X, Y, Z) text1=plt.text(0, 0, 'ghghg',color='black',fontsize=14) plt.text(1, 1, 'Calculation ',color='black',fontsize=14) plt.title('Average ') plt.xlabel('Longtitude ', fontsize=14, color='black') plt.ylabel('Latitude ', fontsize=14, color='black') plt.grid(True) def onselect(eclick, erelease): 'eclick and erelease are matplotlib events at press and release' text1.set_text('Geo ') text1.set_x(eclick.xdata) text1.set_y(eclick.ydata) plt.draw() def toggle_selector(event): print ' Key pressed.' if event.key in ['Q', 'q'] and toggle_selector.RS.active: print ' RectangleSelector deactivated.' toggle_selector.RS.set_active(False) if event.key in ['A', 'a'] and not toggle_selector.RS.active: print ' RectangleSelector activated.' toggle_selector.RS.set_active(True) def movetext(self): print 'clearing plot' text1.set_x(np.random.random(1)) text1.set_y(np.random.random(1)) plt.draw() toggle_selector.RS = RectangleSelector(ax, onselect, drawtype='line') plt.connect('key_press_event', toggle_selector) buttonaxe = plt.axes([0.7, 0.05, 0.1, 0.1]) bbutton = Button(buttonaxe, 'movetext',color='0.85', hovercolor='0.95') bbutton.on_clicked(movetext) Plotter() plt.show() </code></pre> <p>Can someone explain this behaviour? What am i doing wrong? </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.

SQuiL has stopped working due to an internal error.

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