问题 I have in my Excel VBA project, a combobox which uses a range of cells as it's list of items. I have used a filter in it, so that whenever a value is entered, the list shrinks down to the items containing the string, and dropdown list is shown. However, the problem appears, when the dropdown is shown, the navigation keys can't be used to scroll within the items. As soon as the down key is pressed the dropdown list will be filtered again. I guess its happening because the down key while

问题 Using Javascript / jQuery, how can I get automatically repeating keydown events, or equivalent, when someone holds down a key? What I actually want is to be able to check whether a key is down, but from other questions here it looks like that's not possible. The suggested workaround seems to be recording keydown and keyup events and then assuming the key is down if a keydown event has been recorded and no subsequent keyup. That solution runs into a problem in my case. I am designing an online

问题 How can I determine in KeyDown that Ctrl Up was pressed. private void listView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Control && e.KeyCode == Keys.Up) { //do stuff } } can't work, because never both keys are pressed exactly in the same second. You always to at first the Ctrl and then the other one... 回答1: You can check the modifiers of the KeyEventArgs like so: private void listView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Up && e.Modifiers ==

问题 I used KeyDown event and some simple code like if (e.KeyCode == Keys.F1) to capture F1 is pressed on a form BUT if there are some text boxes on the form or if there are some spreadsheets with Dock Fill on the form then the code above gets useless and does nothing. But I want to do something when user presses F1 on this form. so how do we capture a specific keydown event like F1 on the whole form..and I do not want to go to the route that capture the KeyDown of all other controls on the form

DataGridView keydown event not working in C#

问题 DataGridView keydown event is not working when I am editing text inside a cell. I am assigning shortcut Alt+S to save the data, it works when cell is not in edit mode, but if it is in edit mode below code is not working private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyData == (Keys.Alt | Keys.S)) { //save data } } 回答1: Whenever a cell is in edit mode, its hosted control is receiving the KeyDown event instead of the parent DataGridView that contains it. That's why

Python method for reading keypress?

由 对着背影说爱祢 提交于 2019-12-17 03:07:45
问题 I'm new to Python, and I just made a game and a menu in Python. Question is, that using (raw_)input() requires me to press enter after every keypress, I'd like to make it so that pressing down-arrow will instantly select the next menu item, or move down in the game. At the moment, it requires me to like type "down" and then hit enter. I also did quite a lot of research, but I would prefer not to download huge modules (e.g. pygame) just to achieve a single keyDown() method. So are there any
