ownerdrawn

问题 I am trying to add a close button on the tab pages of TabControl and change the color of the close button from light gray to black when mouse hovers over it. However, the color never changes. The DrawEventArgsCustom class is created to indicate that the mouse is hovering over the close button. When it's true, the statement to change the color is executed but color never changes. private void tabControl1_DrawItem(object sender, DrawItemEventArgs e) { try { Rectangle r = e.Bounds; r = this

问题 I have an Owner Drawn List Box in an external application ( America Online ) that I need to get data out of for building a component to assist people with its usability. (the utility will be making access of certain things more simple, etc). Notice My knowledge of C++ is very poor . I am a C# programmer. I have the hWnd to the List Box in question, but it appears to be owner drawn. Using LB_GETTEXT returns bad data, I just get junk (it renders in my debugger as a bunch of chinese characters)

问题 I'm using a ListView in C# to make a grid. I would like to find out a way to be able to highlight a specific cell, programatically. I only need to highlight one cell. I've experimented with Owner Drawn subitems, but using the below code, I get highlighted cells, but no text! Are there any ideas on how to get this working? Thanks for your help. //m_PC.Location is the X,Y coordinates of the highlighted cell. void listView1_DrawSubItem(object sender, DrawListViewSubItemEventArgs e) { if ((e

问题 Is is possible to change the item selection focus color and text color in a TListBox? When themes are not enabled in the project, or the list box style is set to owner-draw, the selection around the item is painted blue, which I believe is globally defined by the system's appearance settings. I would like to change the color of selected items to a custom color. So an example, the result would be something like this: Note the last listbox has been modified in Paint to illustrate the example.

问题 I want to draw a rectangle around a ListView item when the ListView is in Icon mode, so I started reading about owner draw which I thought that it will solve my problem. However, I have also read that owner draw only works in Report mode! Is this still the case under newer versions of Windows (Windows XP and later)? And if this is still the case, then is there another way to draw a rectangle around a ListView item? 回答1: Yes, LVS_OWNERDRAWFIXED style is only meaningful for LVS_REPORT case. But

问题 I am using ObjectListView instead of the standard ListView is because I wanted to word-wrap the columns. I read in several places that the only thing I need to to in order to enable word-wrapping is the set column.wordWrap to true. I did just that, but it doesn't work. What am I missing here? Edit: I realise now that I need to make my column owner drawn. I found this page which sort of tells me what to do, but I'm not sure where to place it in my code. I'm also not quite sure whether I need

问题 I created a custom control whose class has CStatic as base class. Currently I handle the drawing using WM_PAINT event. But there is a strange behavior. When I re-enable the window after disabling it using CWnd::EnableWindow function, it refuses to draw what I written in OnPaint function. It draws the static control instead. I agree that there is this standard method of overriding DrawItem and using SS_OWNERDRAW style. But what's wrong with WM_PAINT ? void XXControl::OnPaint() { CPaintDC

问题 I have a WinForms gui application which has a number of areas to it which I'd like to custom-draw some graphics. These areas would contain controls and be resizeable. I'm currently thinking of inheriting from a TableLayoutPanel and handling onpaint messages. Does this sound like a good way to go or are there other/better options? 回答1: Any Windows Forms control has a Paint event, you don't have to derive your own class. But sure, you can, it helps partitioning the code. Just pick a base class
