![]() Note that the panel’s column span of 2 equals the number of columns in the window’s grid, whereas the buttons added to the panel are placed in three columns in panel’s own grid. Self.outputField = self.addFloatField(value = 0.0,īuttonPanel = self.addPanel(row = 2, column = 0, Self.outputLabel = self.addLabel(text = "Diameter", Self.radiusField = self.addFloatField(value = 0.0, Here is the code for the window setup:ĮasyFrame._init_(self, title = "Sphere Attributes") However, it now adds a panel to the third row, before adding the three buttons to the panel. The code for this program adds the labels and fields to the window’s grid, as before. The result, shown below, exhibits no distracting extra column or alignment issues ( paneldemo2.py). ![]() ![]() This problem could be fixed by stretching either the labels or the fields across two columns in the rows above, but this may cause alignment issues within those rows.Ī better strategy is to add a single rectangular area called a panel to the third row, stretching it across all three columns. For example, consider a window with pairs of labels and entry fields in the first two rows, and three buttons in the third row, as shown below ( paneldemo1.py).īecause each widget must occupy a column in the window’s grid, a third column is necessary for the rightmost button, thereby causing a ragged appearance in the example window. While a two-dimensional grid serves well for laying out widgets in most application windows, there are occasions where the widgets just don’t line up properly.
