Good Morning This is my second attempt to send this email to the AGAR list. I am somewhat confused regarding the correct address to email to. The AGAR info page (https://mail231.csoft.net/mailman/listinfo/agar) says to use [email protected]. However, when I subscribed to the list yesterday the welcome email said to use [email protected]. Hence, I am trying the other address this time since I did not receive a copy of my original posting and it does not show up under the AGAT list archive.

I have made and installed AGAR 1.6.0 without problems. Looking at the examples in the tests directory plus the online documentation it all looks fairly straightforward. I am having a problem with radio buttons. Hence, I think there must be something I am not understanding. I will include some code below, however, firstly I will explain what I am trying to achieve. I create a window of a certain size (300x400). I divide the window vertically into two panes. The upper pane will have a series of 4 radio buttons; the lower pane a notebook with two pages. I have an array of 4 text strings that I use as labels on the radio buttons. I would like the 4 radio buttons aligned horizontally and filling the x-direction. I can get them aligned horizontally, however, I cannot get them to fill the available space in the x-direction. I have tried both placing them in a horizontal box and not. It makes no difference. The code is below. Please note that it is minimal. There are other items that will be displayed within other horizontal and vertical panes and divisions. I have simply deleted that code as it is extraneous to this test. Any thoughts/suggestions would be most appreciated. regards Stephen Meatheringham Canberra, Australia /////////////////////////////////////////////////////////////////////////// #include <agar/core.h> #include <agar/gui.h> #include <stdio.h> int main(int argc, char *argv[]) { int i; AG_Window *win; char *driver = NULL; AG_Pane *vPane; AG_Box *hBox, *div; AG_Notebook *nb; AG_NotebookTab *nt; AG_Radio *rad; if (AG_InitCore(NULL, 0) == -1 || AG_InitGraphics(driver) == -1) return (1); AG_BindStdGlobalKeys(); win = AG_WindowNew(AG_WINDOW_MAIN); AG_WindowSetGeometry(win, 100, 100, 300, 400); // Divide the window into two panes vPane = AG_PaneNewVert(win, AG_PANE_UNMOVABLE | AG_PANE_HFILL); div = vPane->div[0]; // In the upper pane // Create a horizontal box // Add 4 radio buttons, horizontally-oriented and filling the x-direction hBox = AG_BoxNewHoriz(div, AG_BOX_HOMOGENOUS | AG_BOX_HFILL); const char *radioItems[] = { "String1", "String2", "String3", "String4", NULL }; rad = AG_RadioNewFn(hBox, AG_RADIO_HFILL, NULL, AGWINDETACH(win)); AG_RadioSetDisposition(rad, AG_RADIO_HORIZ); AG_RadioItemsFromArray(rad, radioItems); // In the lower pane // Create a notebook with two pages in the bottom section of the window nb = AG_NotebookNew(vPane->div[1], AG_NOTEBOOK_EXPAND); nt = AG_NotebookAdd(nb, "Some text", AG_BOX_VERT); nt = AG_NotebookAdd(nb, "Empty tab", AG_BOX_VERT); AG_NotebookSelect(nb, nt); AG_WindowShow(win); AG_EventLoop(); return (0); }
