How do you overlap widgets/frames in python tkinter?

由 a 夏天 提交于 2019-12-19 19:53:31
问题 I was wondering if this is even possible. My goal is to have a small white box in the bottom right hand corner, on top of a larger text field. The white box will be used as an "info box" while the person scrolls through the text inside of the text field. When I say "text field" I mean Text from tkinter. 回答1: The way to place one widget on top of other widgets is to use the place geometry manager. You can specify an x/y coordinate relative to some other widget, as well as to specify either

Import KML in Maps API V2

问题 I have multiple KML files which are drawn in google earth and contain different routes. Now I'm trying to display those in my android project with Maps API V2. Is there an existing library for importing KML files in your android project and displaying them in maps? I found some code on stack overflow ( How to draw a path on a map using kml file? ) which isn't a library. If there's no library available I'm just going to build this from scratch. 回答1: For now Ill just assume that theres no

How to overlay geom_bar and geom_line plots with different number of elements using ggplot2?

问题 Assuming I have two data.frames with different data but in the same range of x-values a <-data.frame(x=c(1,1,1,2,2,2,3,3,3), y=c(0.3,0.4,0.3,0.2,0.5,0.3,0.4,0.4,0.2), z=c("do","re","mi","do","re","mi","do","re","mi")) b <- data.frame(x=c(1,2,3),y=c(10,15,8)) Both, a and b have the same range of X values (1,2,3) but while a is a data.frame with 9 rows, b is a data.frame with 3 rows. I use geom_bar in order to plot the distribution of values of a, like this: ggplot(a, aes(x=x, y=y, fill=z)) +

How to overlay a button programmatically?

由 北慕城南 提交于 2019-12-19 04:59:46
问题 What I would like to accomplish is to, at runtime, place a button in the middle of the screen, as the very top layer, overlaying anything below it. (It's not big, so it will not completely cover the screen, just whatever happens to be below it.) I looked at creating a custom dialog, however that blocks all other user input. I want all of the views below this new button to act normally and respond to the user, but I just want to add (and later remove) the button above everything. Hopefully

draw is being constantly called in my android map overlay

由 痴心易碎 提交于 2019-12-18 20:14:33
问题 I'm trying to draw a route onto my MapView. I've extended Overlay and implemented the draw() method. The route is displayed properly, although while debugging, I added a breakpoint on draw(), and noticed it is being called constantly. I only want it to be re-drawn if someone moves the map or zooms (the draw take into account these changes when drawing the route) What can cause this ? 回答1: There are two draw methods that can be overridden. void draw(android.graphics.Canvas canvas, MapView

问题 I am trying to implement the MyLocationOverlay class from google maps. However, when I try and use my own locationManager -- I cannot get the overlay to acutally draw on the map. I am wondering if I am doing something wrong. I don't want to call the super method(enbaleMyLocation) of the MyLocationOverlay class because that request updates from the locationManager way too quickly and will eat my battery alive. Here is my code: private class CenterOverlay extends MyLocationOverlay { private
